Amarillo, TX - Sleeping at the wheel is believed to be the cause of a fatal wreck in Dallam County.
Texas state troopers say 70 year-old Rosie Lewis Michalski was driving on US 87 toward Texline Monday night, when she may have fallen asleep.
The pick-up she was driving is said to have veered into the center median before drifting back across the road, over-correcting, and flipping across the roadway.
Michalski was pronounced dead at the scene. Troopers say she was wearing a seat belt.
