A jury found Jesse Jimenez guilty of second degree assault and first degree robbery.
Prosecutors say Jimenez and his friend Trevin King beat up 49-year-old Ronald Whitehead last summer to steal his bike.
Whitehead’s family says he wears a diaper, can no longer swallow, and will never recover from his brain injuries.
“I’d rather have anything happen to me than to see him like this. They took his life,” said Jim Whitehead, the victim’s father.
King took a plea deal in February. He’ll spend ten years in prison.
