RACINE, WI (WTAQ) - A Racine man will spend 23 years in prison for punching a World War II veteran to death, after their vehicles bumped each other in a hospital parking lot.

25-year-old Richard Lewis must also spend 10 years under extended supervision after his prison time.

Lewis was sentenced Thursday by Racine County Circuit Judge Tim Boyle. That was after a jury convicted Lewis of felony murder and battery to the elderly, for killing 88-year-old Albert Paragamian in the lot at Racine’s Wheaton Franciscan-All Saints Hospital.

Prosecutors said their vehicles collided in March of last year – and they then got into a skirmish. It ended when Lewis poked Paragamian in the eye, and the victim fell and hit his head on the ground. He died about a week later.

Paragamian was backing out of a parking space when he struck the Lewis vehicle. Lewis continues to claim his innocence.
