The bodies of 5 young men are found in a car in a violence-wracked city in Mexico

MEXICO CITY (AP) — Mexican authorities say the bodies of five young men have been found stuffed in a vehicle on a dirt road in north-central Mexico. The governor of the state of Guanajuato pledged an “exhaustive” investigation into the killings. The car and the bodies were found Sunday in a rural area on the outskirts of the city of Celaya, which has seen a spate of drug cartel violence in recent years. Local media reported the men had been shot to death. In June, a drug cartel set off a car bomb in Celaya aimed at law enforcement, killing a National Guard officer.
