A 20-year-old man died at a drive-thru after his own car pinned him against a tree as he was leaning out the window to get his fast food order, St. Louis police said Thursday.

The man, identified as Charles Wood Jr. of the St. Louis suburb of Velda City, had pulled up at an angle to the drive-thru window at a Jack in the Box restaurant in south St. Louis on Wednesday, police said, according to the St. Louis Post-Dispatch.

When he opened the car door to reach for his food — which was too far away to grab normally — he placed his car in reverse instead of park and accelerated, causing the car to lurch backward into a tree, police said, according to the newspaper.

Wood was pinned between the car and the tree, causing severe injuries to his head, neck, torso and legs, police said. He was pronounced dead at a hospital.
