The former police chief in the western Mexican state of Sinaloa was found fatally shot Tuesday, police sources told Efe.

The half-naked body of Alfredo Mejia Perez was discovered in Culiacan, the state capital.

Mejia had multiple bullet wounds and the scene was littered with shell casings from an AR-15 assault rifle, the sources said.

Sinaloa's former top cop, a retired military officer commonly known as "Major Mejia," was abducted Monday from his home on the outskirts of Culiacan by several heavily armed assailants.

Security forces moved quickly to cordon off the area where the body was found.

Mejia was accused in 2008 of taking bribes from drug traffickers Arturo and Alfredo Beltran Leyva during his tenure as head of the Sinaloa state police.

Authorities have not speculated on who might have been behind Mejia's murder.

Sinaloa is home to the drug cartel led by fugitive Joaquin "El Chapo" (Shorty) Guzman, but other criminal organizations, including the Los Zetas and Beltran Leyva cartels, also operate in the state.

The Sinaloa cartel, also called the Pacific cartel, is the oldest drug mob in Mexico. EFE
