Robert Leo Kosmal

Patrolman Robert Kosmal was stabbed and shot and killed off duty after stopping his vehicle to break up a fight between two drunks on the side of the road at Albion Street and Cassina Way.

Patrolman Kosmal was able to calm the two men and move them onto the curb. When it seemed as though the men were calm he began to walk back to his car. The two men suddenly attacked him from behind, stabbed him in the back, and then shot him three times.

One of the men was convicted of first degree murder and sentenced to life in prison.

Patrolman Kosmal was survived by his wife and two young children.
