One of the worst accidents he's ever seen.
That's from one of the troopers who worked a deadly wreck in Presidio County.
It happened Tuesday morning on Highway 90, 18 miles west of Marfa.
According to troopers, a severely wounded woman made the 9-1-1 call after a head on collision between two pick-ups.
Troopers say 36-year-old David Osoria fell asleep at the wheel, and drifted into the other lane, hitting another pickup head on.
Osoria and a passenger in the other truck, 19 year-old Nestor Zuniga, were pronounced dead at the scene.
