Investigations

The Criminal Investigations Division is under the command of Captain Tommy Erwin. The primary function of the division is to investigate reports of criminal activity after a crime has been reported to this department. The Criminal Investigations Division also conducts proactive investigations and covert operations in an attempt to deter criminal activity before it occurs.

When you report a crime to the Martin Police Department, a patrol officer will respond to the location of the crime and complete an incident report detailing the crime. The incident report will then be forwarded to criminal investigations on the next business day for review.
