Gunmen kills 10 people in northern Mexico

Prosecutors say gunmen killed nine people at an auto repair shop in the gang-plagued city of Culiacan, while a police investigator was found shot to death near the city's police headquarters.

Culiacan is the capital of northern Sinaloa state - home to the powerful Sinaloa drug cartel and site of an ongoing wave of drug-related violence. Six bullet-ridden bodies were found inside the auto body shop, and three more bodies were found on the street just outside the business.

The state prosecutor's office said in a statement that none of the nine bodies have been identified and no arrests have been made.

A police investigator was found shot to death in his truck near Culiacan's police headquarters.

It was unclear if the same gunmen were involved in his death.
