Criminal Investigations Division

invWhen a Road Patrol Deputy takes a citizen’s report of a burglary, arson or other major crime, it is the responsibility of the Criminal Investigations Division to follow-up and to investigate such crimes.

After the Road Patrol officer receives the call, he makes a determination of how to best handle it and what resources are needed. Many times the deputy may need technical assistance from the detective division to collect trace evidence or process the crime scene. When this is the case, an investigator will respond to help process the scene and may also request additional assistance of an investigator assigned to the crime scene technical unit.

Investigators assist the Road Patrol Deputies with interviews of suspects and witnesses on felony cases. They also coordinate the assembly of the case file that will be utilized during the prosecution. Many times a victim or suspect is from outside of the county and an investigator will assist with interviews that take the patrol officer away from his day to day duties.

Investigators may be assigned to specialized tasks or to special units, such as the multi jurisdictional drug task force, the Wayne County Fire Cause and Origin Team or to the crime scene technical unit. Investigators have been assigned to monitor wire taps, coordinate with Federal or State Law Enforcement Agencies on major cases in Wayne County and to secure prisoners taken into custody on warrants in other states that have to be brought back to the local jurisdiction for prosecution.

Just as in the patrol division, officers in the detective division receive training in specialized fields and utilize very specialized tools to complete the task at hand. Some of the training might entail fingerprint examination, special techniques for interviews, and surveillance techniques. Some of the equipment might be, alternative light sources for detecting trace evidence, infrared and thermal imaging, photography, drug detection, and the CVSA which is used to determine if a person is being deceptive by measuring the amount of stress in a person’s voice and speech patterns.

The criminal investigation process is one of the most important police responses to the problem of crime. Investigators piece together the information they collect from the patrol deputies and from interviews and processing crime scenes. They coordinate with the District Attorney, preparing cases for court. Additionally, not only do they handle Sheriffs cases, the members of the Criminal Investigations Division also assist other police agencies in investigating and preparing their cases.
