Patrolman Michael Thomas Hartzell, 26, was shot and killed in Youngstown, Ohio, on April 29, 2003. Returning to police headquarters, he stopped to run a suspicious vehicle’s license plate. The driver exited and opened fire. Hartzell was taken to St. Elizabeth’s Hospital but died of his wounds.

The suspect, Martin Koliser Jr., fled but was arrested two days later in Pinellas County, Florida, with assistance from the Pinellas County Sheriff’s Department, the Florida Department of Law Enforcement, and the FBI. Koliser was convicted of capital murder in November 2003. Hartzell had served three years with the Youngstown Police Department and is survived by his fiancée, parents, and brother.

Did anyone in the area see Hartzell’s patrol car or the suspicious vehicle near headquarters that day?
