The organisation I used to be presented to for might work location was the office of forensic knowledge. Forensic knowledge usually goes hand in hand with Laws. It specialises in the use of a broad spectral range of sciences to answer questions of interest to legal systems. This may be with regards to criminal offenses, burglary or murder research. Simply put it usually requires the utilization of scientific techniques to retrieve crucial bits of evidence which might be very important to an ongoing police exploration or court case.
The Department of Forensic Knowledge where I did the trick during my location was situated in the green area of the Erasmus Darwin Building on the Clifton campus. Within the last few years the course itself is becoming quiet popular much so that it now not only attracts students from across the United Kingdom but from around the globe too. The activities that are developed by the team are a blend of practical good examples as well as theory in order for the students to understand a few of the certain principles that are involved in this particular field of research. On top of this the office works closely alongside the Nottingham police. This is a huge advantages for the students as it permits them to get first side information of how to start certain methods when it comes to retrieving data.
During my time in the forensic department I got working alongside senior tech Arthur Richards who was simply my supervisor and Paul Mason-Smith who was simply also area of the forensic specialist team. The tasks that we completed ranged from establishing lab practicals to establishing different crime cases for the students to take on in the criminal offenses scene house.
Some of the items one needed to be able to get the jobs done were a common sense of communication and the capability to are part of a more substantial group. Some of the tasks which i carried out individually within my work placement were things such as collecting along the equipment that might be used in the laboratory practicals, charging the camera batteries as well as collecting new equipment from the downstairs store, organising them to be able of their usefulness and storing them away in a suitable location. Other aspects of my tasks did not require establishing practicals or coming up with scenarios but rather to attend discussions that were focusing on medical and security viewpoints of the place of work. These talks positioned a fundamental part of the placements as they proved the problems that may occur if one had not been paying particular attention to the way they were carrying out their tasks. The information obtained from discussions like this one became very useful during the placements. Not only did they permit my to mind my environment while executing might work however they also taught me how to optimise my working capacity by utilizing a few simple illustrations which were provided during the talk.
The tasks that we was undertaking in the 5 weeks of the task positioning not only helped immensely in further producing my sensible skills, but they also help form the key features that a person needs to be able to succeed in any workplace. In my particular workplace the skills that were required from me to be able to work proficiently were a common sense of communication, teamwork and company skills. Fortunately for me, these were some of my better skills.
During my time in the forensics division I also gained exceptional knowledge about some of the techniques which were involved in crime solving. During my placement I carried out two major practicals. Among the techniques that I remember undertaking was The Sneakers and Tool make Impression functional. This practical made up of a collection of 4 activities which collectively were designed to provide one with the opportunity to improve their skills in analyzing tool mark data and collecting sneakers information as well as figuring out the characteristics of boots sole patterns. Tool tag impressions are usually the grades that are left out throughout a burglary. Let's have a house for example. If the idea of entrance is a locked door, the think would most definitely use some kind of tool to force access to the premises. The imprint that is left out in the entranceway is the mark. The role of a forensic scientist is to discover what tool works with with the tool tag that was left on the door. The same idea applies to the sneakers impression which is left behind inside your home. Even if the footwear that is left out is not visible to the naked attention there are certain techniques and equipment that are being used in order to make these imprints apparent. These however will be discussed at a later stage.
Upon successful conclusion of the practical you can:
Demonstrate the competency in casting footprint impressions
Show the capability to use of Electro-static lifting apparatus
Correctly identify lone pattern characteristics
Correctly eliminate exclusive print out using inkless pad
Safely make silicon solid of tool tag impression
Apply theory of recognition of impressions to practical scenario.
Before the students could tackle the exercise I had developed to perform through the practical to be able to see whether everything the functional would work without any faults. Before the going through the useful however we'd to make a suitable scenario that fixed with the useful. The scenario my supervisor and I developed was the following:
Crime Quantity: NTU/221208
Location: 10 College or university Drive, Clifton
Mr. Richard Sole
Burglary at the aforementioned address in a single day break entry gained via back lounge window. Windowpane forced using musical instruments. Climb in steal laptop and mobile phone. Exist as access. There is boots mark in bloom bed below windows and tool markings t world.
2 suspects have been imprisoned and tools retrieved from them. Their shoes in addition has been recovered for even more examination.
Once the scenario was set up my supervisor and I began the practical. The first activity was the casting of an footwear mark in damp sand. This activity was done as a team. It involved sketching the make which was talked about in the criminal offense article with appropriate labelling. Following this, the mark that was visible was coded using the letter coding system. This was necessary to be able to identify the sort of shoe that left behind the imprint.
When the results of the tag returned from the letter coding system we prepared to cast the tag. For this we place casting frame around the mark and inlayed it into the sand to prevent seepage of the plaster. This part needed to be done as a team to be able to ensure that the ensemble did not destruction the mark and that the solid was evenly sent out. To cast the draw I needed to:
Take two times bagged 2kg crownstone plaster and add 500mls of plain tap water to the carrier, massage it well making certain the very best of the tote remained closed. Add further drinking water as necessary considering that the ideal consistency is runny (like pouring cream) without lumps.
When the combination is well mixed, snip from the corner at the bottom of the bad and using trawler pour plaster mix within the cast. During this step my supervisor remarked that the mixture was not to be put straight into the solid as this might destroy fine detail.
Using the trowler lightly tap the top of concoction to ensure plaster settles into every one of the impression and any air pockets are released.
After five minutes using a craft knife inscribe suitable detail in to the cast. This was not necessary in my own case as I was just jogging the practical to be able to see whether everything was going as supposed however after the students started to do this activity they would have to inscribe their initials into the ensemble so they could recognize between their casts. Following the inscriptions the solid was left to have form for 45 minutes.
Once the cast was dry out I carefully tapped the sides of the casting framework to loosen and take it off. Then gently raising the solid and keeping it over the holder brush off unwanted debris with brush so the information on the tread is seen. At this time the solid was completed.
I was advised by a police officer how caused us during the useful that in a real life crime landscape the cast would not be washed. The ensemble plus soil could have been allowed to dried out for at least 48 time before they might be packaged and send intact to forensic scientist lab to be evaluated. The earth or debris mounted on the solid may hold a tiny piece of evidence that could be important in solving an instance or in the case of the aforementioned activity identifying the right suspect which remaining the imprint behind through the burglary incident. The abilities and knowledge that I got away from this activity was to focus on small details such as these that could really make a difference when it comes to solving a criminal offense.
The second activity was the Electro-Static Lifting Equipment. This device is additionally known as ESLA. ESLA contains a high voltage power resource/control product, a nickel-plated material ground aircraft and a metalised lifting medium. It is employed to lift up impressions in dust particles from nearly any surface. It uses static electricity to attract the dust contaminants from the top to a dark-colored lifting film, allowing for a and accurate photograph of the print. A grounding wire attaches to a grounded metal surface and a live wire attaches to a special metallic film. The machine is then turned on. The film is statically attracted to the top and dust debris are attracted to the black part of the film. A roller is provided to even the film over the top. A flashlight is provided as an oblique light source to discover and photograph dirt marks. This process ultimately produces the desired image which in my case was the footwear imprint. The activity was again carried away as a team however since this activity included the utilization of high voltage was done as several three to ensure that everything was cautiously done.
The objective of this activity was to visualise a shoes or boots print that was left behind on a clean surface using the dust particles that continued to be on the floor. The procedure travelled as used:
Using the crime light 80L ( a LED collection light which is utilized for locating information such as fibers, hair or footwear images in a criminal offense field) at a minimal angle we'd to locate the region of shoe particles print to floors sample.
Using the Projectina Dustprint lifter my supervisor raised the dustprint mark
Following this I turned on ESLA and let the current stepped on the steel foil which was covering the of the sneaker dustprint.
After approximately 30 mere seconds ESLA was switched off to lift over the foil and using the criminal offenses light 80L I visualised the still left to determine whether the electrostatic interest drew the dust particle together to form the footwear draw.
After confirming so it did I needed the other colleague sketch the resultant lift up on the offense report.
This delicate technique not only depended on perfection but also reliability. When the students completed the activity, the sketch of the imprint was given a mark with regards to the quality and correctness of the sketch so one had to take extra health care when placing the metallic foil on the dustprint never to destroy the arrangement of the allergens and also while sketching the imprint.
The third activity in the useful was the suspect sneaker contrast. This activity differed from the other two I had formed done so far. Instead of retrieving footwear marks or dustprint grades my job was to look at 2 pairs of suspect shoes I received for comparability. After close exam I observed their code based on the FSS coding linens. The FFS coding sheet supports the info of sneaker types and patterns. Making use of the Bigfoot (a specialised set of equipment used to consider footprints from shoes) I made a printing of each sneaker and tagged them correctly then utilizing a pen I had formed to focus on the regions of interest on the Bigfoot designs which were made. Finally I likened the Bigfoot designs against the Solid which we made during the first activity as well as the ESLA lift produced in the next activity to see whether the pairs were those which were found in the crime world.
I was informed that in real life forensic scientists do that to point out the areas that overlapped with sneakers research that was retrieved from the offense scene. Sometimes there are factors that help identify which shoe corresponded with the printing that was left behind at the criminal offenses scene these include the size of the shoe. A number of the not so evident features are more apparent following conclusion of the Bigfoot analysis. The analysis lets you know a whole lot about the type of person which wore the shoes for example exhausted soles show that the individual using the shoes must have done a whole lot of walking. Distorted sole patterns arise due to the weight which is placed on them. It is little hints such as these which slim the amount of suspects down.
The final activity of the functional was the Tool Markings activity. What I got to do here was to verify the UPVC (a material used in making house windows, gutters as well as doors) portions with the tool symbol damage with them. Using silicon casting package I made a solid of the markings and allowed those to dry for approximately quarter-hour before eliminating the from the real wood. Once the silicon cast possessed dried I took it and likened it to the various tools which were recovered from the suspects to see if the tools matched up the cast. To recognize the features and style of the tool make and the cast I used a magnifier. This sensitive method required a lot of fortitude and a reliable hands as it required a while until align the various tools with the solid however once this was done I could confirm which tool was used to make the tool mark. The final stage of this activity was to sketch and label the tool that made the tool mark. The information gathered from the sensible was tabulated and submitted away. The tabulated results would then be employed by the member of the coaching team to compare them contrary to the results the students would gather. Following the completion of the practical I used to be asked by my supervisor to prepare a stand of results using the computer. This desk was to be used by the students to complete their obtained results. The stand also included a couple of question that they needed to answer.
During my second week in the placement I was released to the criminal offenses scene house which was also situated on Clifton campus. The Offense scene house had been established very recently since it was officially an accommodation for postgraduate. It was now used as a sort of training facility that simulated true to life situation. The house's propose was for the students to hone their analysis and retrieval skills as well as get used to the idea of operating in a genuine life surrounding. The house itself was equipped with CCTV video cameras to be able to monitor the students while these were undertaking various scenarios. The forensic knowledge department worked strongly alongside the Nottinghamshire law enforcement as stated earlier. The benefits of this was of course the fact that students would get advice from experienced officials on how to deal with murder investigation, burglary circumstances and drug queries.
My role as an helper technician was to prepare the house for the correct activity that would take place. The scenario which i was asked to create was a Drug search activity which was scheduled to take place during the week. I used to be working alongside my supervisor and an associate of the Nottinghamshire police force who explained that activity was calm complex in a real medicine search. Sometimes the places the drugs were covered were unimaginable that's why you had to believe like a legal in order to find them. For health and safety measures the things which were to be used for the exercise weren't real drugs.
Once the drugs were all put away I went back to the office buildings and designed a table using Microsoft term which held the information of the several kinds of drugs and equipment that were used and the complete location they had been positioned in the criminal offenses scene house. This is done in order to keep track of the items the students retrieved also to keep in mind which items have been placed where in the house.
On the next day while the students were starting the Medicine search activity my supervisor and I went in to the CCTV room in order to screen the student's progress. My supervisor familiarised me with the operating system and different functions which were necessary to be able to regulate each CCTV independently. After I was comfortable with working the CCTVs I was left with the task of monitoring the actions of the students as these were doing the activity. During this I had fashioned to notice down any action which travelled against the code of conduct that they had been taught during their lectures. When joining a crime picture it is very important the particular one wears the correct equipment such as a protective collection which addresses you from check out toe, gloves and a cover up. This is to avoid you from covering the world with your fingerprints, hair strains or saliva traces. A number of the students made faults such as the ones pointed out and it was precisely these acts which i had to write done in the log publication. While I was watching I noticed that a few of the students were retrieving the items quicker however in turn they didn't find all of them. The items they didn't find or alternatively overlooked were the items which I put in the greater apparent locations such as under the carpet. The others were retrieving the items at a slower speed however they managed to find all of them. This highlighted the fact that patience actually was a virtue. After they got retrieved everything the mysterious samples of drugs were cut back to the lab for trials.
The other activity which occurred in the offense world house towards the end of the week was the murder world activity. The planning of this activity included using life size dummies which looked shockingly real. Depending on the circumstance the dummy was either male or female. The dummy we used that week was the guy dummy which acquired cut wrists and a slit throat. It had been positioned in the double bed room. During this activity the students needed to examine the room the "victim" was found in for fibre traces, shoes and any DNA traces. Once the room was effectively searched the students would get back to the lab to see one of the associates of personnel demonstrating how to properly carry a corpse. Through the demonstration it became apparent to numerous students including myself that the transportation of any corpse from a criminal offense scene was not as straight forward as it looked like. Before the corpse was put in a body handbag the limbs had to be wrapped in forensic data bags as they may hold crucial pieces of evidence that could be uncovered through the autopsies which take place in the forensic labs.
I mentioned previously that within being an helper technician I needed to occur in a Health and safety talk to be able to familiarise myself with the daily dangers which encompassed the workplaces. The talk lifted some interesting items of about the dangers of carelessness during work or how the preparations of items could cause serious problems during evacuation. The talk's main target was about preserving a good workplace at all times. It confirmed how one could increase their work efficiency by rearranging their office, prioritising the items they need in order of their usefulness at that time. The talk continued to explain the necessity of taking short breaks when focusing on the computer. The breaks allows one to take your gaze from the screen thus easing the strain on your eyes. A general rule of thumb is to check out the distance as this relaxes your ciliary muscles. Moving about of these small breaks is also very helpful as it offers you the chance to get up from your seat and stretch the muscles. These few simple assignments proved to be a very useful set of skills nonetheless as I'm writing this record.
Throughout the practicals and cases that my supervisor, colleague and I did, I felt our teamwork and communication kept improving to the point were it was almost perfect. This in turn greatly enhanced the speed of completing various tasks and practicals as there was less problems. After some time I had been even able to help the students with small technical complications of the cameras.
The other major useful that I well prepared and analyzed was the Inked Fingerprint sensible. Fingerprints are taken for a number of reasons a few of them are:
To establish somebody's identity.
To find out whether someone has a criminal record.
In the situation of migration the house office takes fingerprints to recognize whether one is illegal in the united states.
To clear a suspect of committing a criminal offense.
Using fingerprints as information in a judge case.
The Police use them to determine whether a person has already established any previous convictions.
This sensible also involved several different levels which when linked jointly provided me with the opportunity to develop an understanding of the number of fingerprint style types. Also while doing this sensible my supervisor released me to the task that is involved in taking fingerprints from genuine crime suspects. Once I had developed completed this exercise I recognized the type of fingerprint characteristics and I could take care of fingerprint equipment as well as taking fingerprints from individuals. Prior to starting the procedure however I was made aware of medical and safety aspects of this practical. Even though the risks that encompassed were nominal I had to wear a laboratory coat to ensure that no ink came in touch with my clothing. The first area of the sensible required teamwork as a result I caused my supervisor. This part of the sensible divided the groups into two assignments. One person were required to supervise and take the designs whereas the other was required to expect the role of the think who was having their fingerprints used. With regard to understanding the useful I assumed the role of supervision. The materials which were used included:
National arrest form
Card form holder
In order for acquiring the best possible images I had formed to ensure that my hands were thoroughly washed, dried out and clear of perspiration, the printer ink plate was clean and inked correctly and my wrists and fingers were relaxed making sure not to aids the prints by adding pressure to the dish as this only brings about inaccuracy. Once the precautions were place we went into the preparation procedure that was as adopted:
Complete the details on the form
Fold the newspaper over the lines indicated
Place the form under the fingerprint cards so that this leaves the right palm impression obvious.
Dot 8 to 12 evenly spaced out spots of ink on the dish. Once it has been done roll the printer ink out uniformly until it has a semi mat end.
Take a test impression on the ordinary A4 newspaper. If too much ink is used on the paper clogging will form between your ridges if however too little is utilized the ridges can look grey.
The goal in each case was to produce a fingerprint which experienced sharp black ridges and white interspaces.
The trick of removing extra printer ink from the dish was to place a blank piece of paper over it and pass the roller over it until the plate had an even layer of printer ink.
As part of the health and protection precautions I had fashioned to bear in mind to check on for cuts, skin condition and the quality of the ridges. This was to ensure that the ink would go into the reductions and cause contamination or agitate your skin. Once the practical had been create we experienced the sensible as followed:
The "rolled" impressions were obtained by moving the digit through 180 diplomas from nail edge to nail border for the complete region of rigid aspect on the internal surface of the finger to be registered. My supervisor suggested that it's recommended to do this slowly but surely as it produces a much better quality of fingerprint.
Take the fingerprints starting with the right thumb and working the right path across the form, taking each finger in turn to the right little finger ensuring the right digit appears in the best space.
After concluding the right palm change the fingerprint form in the holder in that manner as to allow the remaining hand prints to be taken. Once it's been repositioned do it again the same steps with the remaining hand taking caution to put the digits.
The reason the basic impressions are taken before the rolled impressions is to certify that the rolled impressions have been used the correct manner on the fingerprint form. I was told that they may prove very helpful to a fingerprint office it is therefore very important that they are recorded within the area chosen for these people, nor overlap onto other lines or printing. When they were taken I had formed to move the proper execution down in the holder to expose the ordinary expression section. When this is performed I took each of the suspect's hands and pressed all four fingers jointly onto the printer ink plate, lifted them off and onto the appropriate space and pressed all four fingers down alongside one another. After this I took them of and used the same technique to obtain the thumb images.
The final part of the functional was to take the palm prints. While using the printer ink roller I protected the whole palm and finger surface of my supervisor with a covering of ink. Finally I had developed done this I placed the heel of the palm onto the paper and drew the side again over the above the roller to the fingertips, exerting a little pressure. After the practical was complete I set aside the gear and well prepared the lab for research students that were working on a job that involved the use of cams and 80L offense lights.
I realised that throughout the positioning my company and communication skills placed improving. Because of this it made me a far more reliable person. The many tasks which were assigned to me by my supervisor reflected this. Being accountable for establishing practicals, burning CCTV footage for later use and organizing equipment for research students in addition has increased my self-confidence of managing jobs by my do it yourself. The health and safety talk in addition has helped as it made me alert to the hazards that I used to ignore before.
Having completed my position at the forensic department I must say that is a priceless experience for me personally. The placement has not only given me an information in your day to day activities that encompass a forensic scientist but it has additionally helped in further expanding the key traits and understandings that one needs in order to excel in any given place of work. I think that the way I carried out the tasks which were assigned if you ask me had a direct influence on my personal development and of course vice versa. Judging by this I'd like to think that I completed my daily responsibilities and completed those to the best of my ability. My frame of mind also contributed to my development. Generally I was quiet quite happy with my workplace. At the start it took some time to adapt to certain aspects of the placement such as timekeeping, sticking to the deadlines and schedules and bearing the responsibility of establishing practicals. These needs and responsibilities required that I put to learn quickly and adjust to be able to prevail in this place of work.
I realised during the placement that one of my weaknesses was the reliability and trustworthiness of the practicals I had developed prepared. This is only natural as forensic science had not been my area of expertise however since I requested this placement it recommended that I needed to check out the same conduct and set up the practicals in the same manner as a forensic specialist would do. My supervisor also offered me the advice of taking my time while establishing the practicals. To be able to resolve this matter I paid particular attention to the other technicians while they were setting up practicals. As a result of this the dependability of my practicals better immensely during the period of the placement. Among my stronger property that my supervisor commended on was my organising ability and initiative. I could resolve a concern that occurred with the burning of the CCTV recordings. The recordings were usually burnt on the CD however for some reason when these were empty even although getting rid of of the CCTV recordings was successful. I recommended the thought of uploading the recordings on an external hard drive. This possessed lots of benefits as it was capable of storing a lot more Giga bytes of CCTV recordings and over time would work away cheaper than to keep purchasing Disc ROMs. Overall I would say that placement has transformed me into a far more accountable, reliable and punctual individual who can work as part of any team, as well as work singularly in order to complete the duty that is set out to the best of his ability.
