A Texas man drunkenly ran a person over and then drove with the “mangled corpse” in his passenger seat for at least a half-mile — before stopping at a beer garden, police said.

Paul Joseph Garcia, 24, allegedly rammed into a pedestrian pushing a shopping cart at about 10:40 p.m. Saturday in South Austin, the Austin American-Statesman reported on Tuesday.

The victim went through the 2014 Ford Focus’ windshield and suffered traumatic injuries to the head, with some body parts becoming detached, according to an arrest affidavit cited by the newspaper.

But Garcia kept driving “with a mangled corpse in the vehicle,” the document states.

Witnesses saw Garcia park his car about a half-mile from the scene of the accident and then calmly get out, police said.

He then walked into the South Austin Beer Garden barefoot — “in a manner that caught the attention of the other patrons,” the affidavit said. He wasn’t served any alcohol at the bar.

Debris, including car and body parts, lined the road from the scene of the crash to where the car stopped, the document said.

Garcia had evidence on his body that matched the blood and body tissue found coating the inside of the vehicle, cops said.

Officers conducted a sobriety test on him and he was charged with intoxication manslaughter and accident involving injury.

He was being held Tuesday on $110,000 bail.
