A man whose lifeless body was found Saturday dangling from an oven vent inside a Marrero store essentially suffocated as he tried to break into the business, the Jefferson Parish Coroner’s Office said Monday.

An autopsy found Ken Singleton, 44, died of positional asphyxia, said Kim DiLeo, a forensic investigator with the Coroner’s Office. Positional asphyxia means breathing is restricted because of the way a person’s body is contorted.

The store’s owner found him shortly after 9 a.m. Saturday when he arrived to open the business for the day, the Jefferson Parish Sheriff’s Office said.

DiLeo could not say how long Singleton might have been in the vent before he was discovered.

Investigators said Singleton was a would-be burglar who was trying to get into the store by climbing through its ventilation system. Authorities found an apparent entry point on the roof where they discovered the upper half of Singleton’s body.

Members of the Marrero Ragusa Volunteer Fire Department removed his body, and he was pronounced dead on the scene.

The store remained closed Monday. Attempts to contact the owner were unsuccessful.
