AURORA, Colo. — An Aurora man was found guilty last week of beating his 84-year-old grandfather to death during an argument that started over some shrimp.

Jason Vanbommel, 34, was found guilty of reckless manslaughter and first-degree assault of an at-risk adult, among other charges. Both charges are felonies.

On Dec. 29, 2015, Vanbommel’s grandmother was preparing dinner when Vanbommel began arguing with her over the shrimp she planned to prepare, the 18th Judicial District Attorney’s Office said Thursday.

Frans Vanbommel, 84, interrupted and told Jason Vanbommel to be respectful of his grandmother. Jason Vanbommel reportedly flew into a rage, throwing things and yelling profanities, the district attorney’s office said.

When Frans Vanbommel tried to call 911, Jason Vanbommel began punching his grandfather in the head with full-strength blows, the district attorney’s office said.

When Frans Vanbommel fell to the floor, Jason Vanbommel kicked him in the torso, fracturing his ribs. When Jason Vanbommel left the home, police were called.

The condition of Frans Vanbommel deteriorated after he was admitted to a hospital. He died Jan. 6.

Jason Vanbommel was found guilty April 13. On Tuesday, a judge determined he is a habitual criminal that might make him eligible for stronger penalties.

He faces a sentence ranging from 16 to 48 years. A sentencing hearing is scheduled for June 16.
