Authorities found the dismembered bodies of 37 people stuffed into bags and dumped on a highway near the northern industrial city of Monterrey in what appeared to be part of a string of brutal drug gang killings, local media reported.
The bodies were found in the early hours of Sunday on a highway, sparking a large deployment of local, state and military officials to the scene, daily Excelsior reported on its website. Other national newspapers also reported 37 dead.
The report follows a string of atrocities, including 18 people who were found decapitated and dismembered near Mexico's second-largest city, Guadalajara, on Wednesday.
Authorities in Nuevo Leon, the home state of Monterrey, could not immediately be reached for comment.
