YOUNGSTOWN, Ohio - Youngstown Police Officers took time this morning to remember a fellow officer who gave the last full measure of devotion thirteen years ago on this date.

A call went out over the police radio to observe a moment of silence at 2:19 a.m.,today  which was the exact time on on April 29, 2003 that Officer Michael Hartzell was killed in the line of duty on a downtown street.

Patrolman Hartzell was gunned down during an unprovoked attack as he sat in his police car near Powers Auditorium.

Martin Koliser was convicted of the crime and sent to Ohio's death row. He later committed suicide in his jail cell.

Officer Hartzell's memory lives on through the Michael T. Hartzell Memorial Scholarship at YSU.

Hartzell is among 11 other Youngstown Police Officers who have died in the line of duty since 1891.
