Prosecutors in northern Mexico say five headless bodies have been left in front of a funeral home.

The prosecutors' office in the northern border state of Chihuahua says the killings occurred in the town of Guachochi. It's part of an area is known as "the golden triangle" because of the amount of drug production there.

The office said four men arrived in a pickup truck Tuesday at the Guemar funeral home and left two headless bodies riddled with bullets.

Hours later, another pickup arrived at the same funeral home and left three more headless bodies. The driver of the truck said he had found the bodies on a road and brought them to the funeral home.

Four of the victims were identified by relatives.
