Team Leader/First Attending Officer (FAO)
The team leader is the person that keeps control at the scene as well as safety and security, the team leader also makes sure that all the other personnel are wearing the correct equipment. This ensure that any hazards that may be present at the scene aren't going to harm anyone. The Team Leader will also create a common approach path (CAP), this is the best route to walk around the crime scene so that you don't affect any possible evidence which is potentially present. There will also be a designated area where all important information can be transferred to the appropriate person to be investigated, they will also control who will be able to enter and leave the crime scene by logging them in and out. The FAO will also speak to any potential suspects/witnesses at the crime scene to find out any information or give first and give first aid to anyone that is potentially injured from the crime that has been committed; this will be carried out before any other emergency service is called. Once the FAO feels as though its necessary they will then start to tape off the crime scene so that any evidence can be protected and not contaminated Finally the Team Leader will close the crime scene once all relevant information and evidence has been found.
Police
The police are called when a potential crime is committed and when the police arrive this could either be a first attending officer or multiple officers depending on how serious the crime scene is, the main purpose of the police when they arrive at the crime scene is to make sure that whatever witnesses or potential suspects that are there are interviewed and checked for any potential injuries, the police also need to tape the scene and remove any unwanted attention like press and the media; also the police need to preserve any evidence so that none of it becomes contaminated.
Photographer and Log Recorder
The Photographer and Log Recorder's first job is to photograph the whole area before anyone enters, any victims, crowds or vehicles, they also need to use a measuring scale where appropriate. Also when a piece of evidence is found they need to measure and photograph that as well before it is taken to be examined, finally they have to have a photo log and possibly make any sketch's if needed.
Detective
Detectives work with all people throughout an investigation and the way that they do this is speaking with the police, public, witnesses and suspects. Whatever information the detective then recieves they need to log and preserve this evidence so that it can either be presented in court or further tests can be carried out by specialists teams to find out more information.
Sketch Preparer
the Sketch preparer's job is to sketch a picture of the whole scene, sketch any of the major evidence that' been found and when a sketch has been made to note down whether its to scale or not.
Prosecution
The prosecutor is the person that decides on whether the victim(s) are either guilty or not and the way that they come to this conclusion is by working closely with other investigation teams, to find out information about what has happened when the crime scene has been investigated. the prosecutor will come to a conclusion once they have looked at all the evidence and would decide if the suspect(s) is either guilty or not. The prosecutor throughout a trial will ask the suspect(s) questions relevant to the evidence that they have found to try and prove them guilty, the prosecutor will then back themselves up by linking there evidence to other investigation teams that will have been involved with the case.
Evidence Recorder/Recovery
The Evidence Recorder/Recovery need to make sure that they have a photographed picture of the evidence that they have got, describe where the location of the evidence was and give a description as well as place it in the correct bag or envelope. They need to put there signature, time and date on the piece of evidence that they have collected and finally use all the correct personal protective equipment (PPE).
Scenes of Crime Officer (SOCO)
SOCO's are the team that are called to the crime scene to collect evidence as well as picture the crime scene and start to picture an idea of what happened, once the crime scene has been photographed the SOCO's then move onto finding evidence, taking a picture as well as measuring the size of the evidence; then preserving the evidence in the correct bag and either sending it to any specialist team or keeping it themselves to analyse.
Specialists
The Specialists are very rarely used but when they are they get called in by whom ever is in charge of the case, the Specialists are paid for there service because of how much variety there is now to forensic science. But depending on what type of Specialists you need to get involved with there is quite a few areas that they do; and these are bomb technician, criminalist, medical examiner or surveyor.
Defence team
The defence team's main job is to either minimise the sentence or provide enough evidence to prove to the prosecutor and jury that their defendant is innocent, the defence team consists of three members, a barrister, solicitor and a legal executive. The first member that gets presented with the case is the legal executive, they will overlook the defendants case and decide whether they want to go forth with the case; this is where if the legal executive will take on the case they will contact their solicitor. The solicitor will then organise everything for the defence team on the day the trial, this is where the barrister is involved because they are the one that introduces the defendant;barristers are mainly used in higher profile investigations like murders.
Depending on what type of crime has been committed that would determine what type of response team would need to be sent out for example, if a drugs raid was carried out at a house you wouldn't need a massive response team because the evidence would be easy to seize and you would most likely know your suspect. Where as if it was a murder case you will need a bigger team because there will be a lot more evidence to collect, you will need to collect more information and you may need to get extra specialist teams in to help with the investigation.
The people involved in the Billie-Jo Jenkins case.
In the Billie-Jo case there was a few people involved to try and help solve the case the first people who where at the crime scene where the police, the police's job would be to secure the area and gather any information that would be needed; so it can be passed on to the relevant person. The next people that where involved in the case where forensics who's job is to collect evidence and preserve it by placing them in the correct bags, sealing them so that the evidence can be taken away for further analysis; for example Sion Jenkins coat.
Also in the Billie-Jo Jenkins case there was a lot of lawyers when the case was taken to court there role was to defend Sion Jenkins and try to prove that he was innocent, the lawyers that where present at the court trial used papers to appeal Sion Jenkins at the Lewes crown court. Brendan Salsbury was one of Jenkins solicitors who argued the point that the media was too involved, which lead him to put in an appeal about the newspapers.
