A man died at a Houston hospital Monday, three days after he was hurt in a motorcycle crash in Polk County.

DPS says 66-year-old Herman William Bullock of Point Blank was pronounced dead at 11:55 a.m. Monday.

The accident happened at 2:44 p.m. Friday on US 190, three miles east of Onalaska. Bullock was driving his motorcycle heading west the highway when a 2002 Ford F150 stopped to make a left turn onto Forest Hills Loop. Bullock then crashed into the back of the Ford.

The driver of the Ford, Rolando Lazaro Carreno of Onalaska, was uninjured.

Bullock was not wearing a helmet, DPS said.
