Patrolman Richard James O’Brien, 33, was killed in the line of duty on February 9, 1982, during a traffic stop at 8110 South Morgan Street in Chicago. He and his partner, Patrolman William Peter Fahey, had stopped a brown 1978 Chevy Impala driven by Jackie F. Wilson, 21, with his brother Andrew Wilson, 29, also in the car. A confrontation began when Jackie refused to produce a driver’s license and Fahey ordered Andrew out after seeing a suspicious object.

Believing O’Brien still to be moving, Jackie reportedly called to his brother, who then shot O’Brien two more times, in the arm and the hip. The brothers fled, circled back to take both officers’ firearms, and left the scene; they were later apprehended and convicted. Their initial death sentences were commuted to life in prison by Governor George Ryan in 2003. O’Brien is memorialized on the Illinois Police Officers Memorial Wall and the National Law Enforcement Officers Memorial Wall.
