Jason Vanbommel

Frans Vanbommel, 84, interceded in an argument and told his grandson to be respectful of his grandmother. Prosecutors said Jason Vanbommel flew into a rage, throwing things and yelling profanities. When the grandfather tried to use the phone to call 911, the grandson began punching him in the head with “full-strength blows.” When Frans Vanbommel fell to the floor, the grandson kicked him in the torso, fracturing his ribs.
