Authorities in Louisiana are investigating a “suspicious death” after a body was found in a walk-in freezer at an Arby’s restaurant in New Iberia, police said.

The New Iberia Police Department said the female victim was an employee at the restaurant on E. Admiral Doyle Drive, according to KADN. Her cause of death has not yet been determined.

“So it was an employee that discovered the female deceased inside the cooler, (and) the deceased is an employee of the restaurant,” New Iberia Police Capt. Leland Laseter told the local station.
