PIEDRAS NEGRAS, Mexico — Four young men have been found decapitated in northern Mexico.
Durango state police say the heads were found on the hood of a pickup truck left in a shopping center parking lot in the city of Gomez Palacio late Saturday.
A Durango state police officer spoke on condition of anonymity because he is not allowed to discuss the case. He says the bodies were found in the truck bed.
A message on the windshield allegedly signed by the Zetas gang said the victims were involved in an attack at a bar in the neighboring city of Torreon that killed eight people earlier Saturday.
The officer said Sunday that relatives told authorities the four men killed, ages 18 to 20, were university students in Gomez Palacio.
