NIXA, Mo. (AP) — Police in the southwest Missouri town of Nixa are investigating how a decomposed body ended up in the back seat of a car parked at fast-food restaurant.

Nixa spokeswoman Jill Finney says police were called to a Wendy’s restaurant early Thursday after the body was found in a car that had been in the parking lot for several days.

Finney says the body was so badly decomposed it was nearly unrecognizable but it is apparently a male.

The Springfield News-Leader reports that Finney says foul play has not been ruled out. No other details were released.
