(CNN) -- The alleged leader of the Beltran Leyva drug trafficking organization was killed in a shootout with federal forces in northern Mexico, state media reported.
Pedro Roberto Velazquez Amador, alias "La Pina," was killed in a shootout Wednesday morning, hours after a military convoy patrolling the San Pedro area in Monterrey was attacked by gunmen.
Velazquez was killed in the subsequent shootout, state-run Notimex news agency reported.
Pictures from a local newspaper showed the body of a man believed to be in his 30s and said to be Velazquez, lying in a puddle of water with a firearm in his hand.
Velazquez is the alleged leader of the Beltran Leyva cartel in San Pedro, according to the National Defense Secretary of Mexico.
However, recent reports say the fractured Beltran Leyva cartel has been splintered into warring groups.
Mexican-American drug trafficker Edgar Valdez, known by his moniker "La Barbie" for his light complexion and blue eyes, is claiming leadership over the cartel.
The military says it seized three small arms, 30 rounds of ammunition, a laptop and two vehicles during the shootout.
In December 2009, the co-founder of the Beltran Leyva cartel Arturo Beltrán Leyva, was killed in a luxurious apartment community during a 90-minute shootout with the Mexican navy.
The Mayor of Cancun, Greg Sanchez, was detained by federal police Tuesday at the airport on suspicions of money laundering and allegedly helping protect the Beltran Leyva and Los Zetas cartel.
