Detectives

Detectives/FBI is a member of the police force that would potentially be involved within an investigation. The detective will attend the crime scene after the first attending officer has analysed the scene and called for the appropriate authority sectors that need to be involved. The detective will have a superior responsibility than police officers within the region. A detective will be held responsible for ensuring that the crime scene is securely cornered off by the public, and that the area cornered off is large enough ensuring no evidence is outside of the scene.  They also supervise/run the preliminary investigation and analyse any significant information brought to their attention by police officers. They will then lead the follow up investigation and delegate roles to other police officers, ensuring that they are carrying out their roles and responsibilities correctly. The detective will be follow the investigation closely, ensuring that all lines of enquiry are thoroughly investigated and analysing any intelligence.

Detectives will be involved in a variety of different investigations that are of a high profile, such as serial murder or rape. The police officers will initially analyse the crime scene and depending upon the information they obtain determines whether they believe the detectives are needed to assist the investigation. Detectives are involved in minor investigations, such as theft or vandalism.

Referring to the Paul Morin case there were two different detectives involved, this was because the investigation first begun in York, therefore a detective from the York Regional Police conducted and organised the investigation. However once the body was found with Durham, Detective Shephard took over. The role of the detective then changed as it had now become a murder investigation rather than a missing persons investigation. Therefore Detective Shephard objectives changed as their fundamental aim was to identify and then locate the killer of Christine Jessop, whereas the objective declared by Detective Fitzpatrick was to locate Christine Jessop as it was simply considered a missing persons case.

FBI profiler John Douglas was involved within the investigation when the body of Christine Jessop was found and they had found enough evidence to suggest particular characteristics of the killer. Douglas created a profile stating different characteristics of what the police and public should be looking out for. However unknown to the public the police manipulated the profile to fit the characteristics of Paul Morin.
