Over the weekend, 15 bodies were discovered by police in the Mexican resort town of Acapulco, which has become the latest site of fierce drug-gang violence in Mexico.
All but one of the bodies were decapitated.
The victims, all men, were found outside a shopping centre on Saturday along with a handwritten note signed by Mexico's most wanted man, "Shorty" Guzman.
Guzman is the head of the Sinaloa cartel, thought to be fighting off rivals for control of the area's drug trade.
Acapulco has become the latest battle zone of fierce drug- related gang violence in Mexico, with at least 27 bodies being found between Friday and Saturday.
Mexico's drug war has claimed 30,000 lives in the last four years.
