CONROE, Texas -

A man accused of killing a grandmother in an early-morning crash is facing an intoxication manslaughter charge.

Police charged Richard Compton with intoxication manslaughter for allegedly broadsiding a family of four that was in an SUV on Highway 105 near Navajo early Sunday morning.

Investigators said the family's car rolled multiple times, while Compton's truck came to rest at a power pole.

Police said Compton took off shortly after the crash.

Investigators found him at a local hospital being treated for a broken arm. He was arrested after he was treated.

Investigators said the grandma was in the backseat with her granddaughter and two other relatives were in the front seat. Officials did not release the conditions of the other three family members.
