A Cape Girardeau jury found a Perryville, Mo., man guilty of involuntary manslaughter Thursday.

After 40 minutes of deliberation, the jury convicted Randy G. Stone, 30, finding his actions caused the death of David A. Grass on June 25, 2006.

Stone had been driving southbound on Route B near Cinque Holmes Bridge in Perry County in the early morning hours when his Pontiac Grand Prix failed to negotiate a curve and crossed the center line, according to a probable-cause statement by the Missouri State Highway Patrol.

Stone's vehicle struck a white Ford F-150 head on, and the driver of that vehicle, Grass, died later that evening as a result of his injuries, according to the sworn statement.

Involuntary manslaughter is a class C felony, punishable by up to seven years in prison.
