WALLER, Texas -- A man has died after he was struck by a vehicle while helping his daughter following a crash in Waller, Texas.
Police said the victim, who has not been named, fell asleep at the wheel while driving with his son and daughter in the backseat. A family friend was also in the front of the vehicle with the victim.
Their vehicle was headed down the eastbound lanes of U.S. 290, just before FM 362, when the man apparently drifted off the road and slammed into a guardrail.

The victim's daughter was thrown from the vehicle. Police said when the man tried to help his daughter, a second vehicle passing the crash slammed into him.
