Chapter 19 Section 7 Establishment of a task force

This three-generation murder case shocked the entire community. The residents hoped to solve the case immediately, and their anxiety was beyond words.On the first day we arrived in Derby to collect evidence, the local community newspaper called me the most authoritative and well-known criminal forensic expert in the world; a week later, the case did not make any progress, and the newspaper changed its name to me as a well-known forensic forensic expert; For three weeks, when the newspapers reported on this deadlocked murder case, they only referred to me as a criminal forensic expert. If the case was not solved in another month, I might be called a forensic forensic officer.

I fully understand everyone's desire to solve the case as soon as possible, but as a criminal forensics officer, I also know that this expectation is unrealistic.The general public demanded to solve the case immediately, and the higher-ups demanded to solve the case immediately, just like solving the case within a time limit in China, which is impossible in modern scientific investigation; If the case is not mature, or sufficient evidence has not been discovered, the case cannot be declared solved.In some cases, as long as the investigators arrive at the scene within five minutes, the suspect can be found, arrested along the line, and the case is declared solved.Every case is different, and the deadline cannot be solved uniformly.

In addition to community pressure, investigators and forensics personnel must also appease family members, deal with media reporters who follow all day long and record what they hear, and more importantly, forensic personnel must also concentrate on finding clues from physical evidence. Regardless of any conflicts or pressures, forensic personnel must stick to their principles and find all evidence related to the case, whether it is positive evidence proving the crime of the investigation object or counter-evidence proving the innocence of the object of investigation, they must be treated equally.If the direction of the investigation is guided by evidence, there will not be too much deviation. If the investigation is guided by personal intuition, the possibility of mistakes is quite large, and sometimes unjust imprisonment will occur.

In order to resolve these conflicts and concentrate on solving the case, we organized the investigators and forensic personnel into a special case team to reach a consensus, determine the direction, and divide and cooperate. Information management is an important task of the task force.In recent years, information management has become more and more important in criminal investigation.In the period of agricultural society, any district police officer knew all the residents in the area. Once a homicide happened, just ask the district police officer and they would know everything.However, with social changes and frequent population changes, the district police officers have been reduced to a part of the system, and the estrangement of residents is deep.Information management fills in these vacancies, integrating fingerprint files, school records, and various government databases, allowing investigators to gain a more detailed understanding of the suspect's background information.

As far as this case is concerned, the city of Derby has more than 30,000 residents, so we can first take Jiujiu.5% of the residents were excluded from the suspect list, and then the remaining ○.Five percent of the population means that the suspect may be addicted to drugs, good at playing basketball, and has a criminal record for theft. The police officers in the information room will immediately print out a list of those who meet the profile requirements, providing investigators with clues to find out the possibility of their involvement in the case.
