The car went airborne before barrel-rolling through a yard. The black Honda Accord ended up on its roof.

According to the criminal complaint, responding officers found Degraffenreid still in the vehicle. They say he was able to unfasten his seat belt and the first responders pulled him out.

As he was telling them his girlfriend was missing, police say they “detected a strong odor of an alcoholic beverage emanating from Tyler.”
