Mexican marines captured an alleged Zeta leader suspected in hundreds of murders, including the 2010 killing of an American man jet skiing on Falcon Lake.
Though handcuffed suspect -- nicknamed Ardilla, which is Spanish for squirrel --was defiant. He gave thumbs up sign when presented to Mexican media.
A spokesman for the Mexican Navy says Salvador Martinez Escobedo, 31, is suspected of killing 50 people with his own hands and ordering the murders of hundreds more, including American David Hartley.
Hartley disappeared on Falcon Lake while Jet skiing with his wife in September 2010. She told investigators gunmen attacked the couple.
According to authorities, the Zeta leader also ordered the beheading of the Mexican police investigator handling the Hartley case.
The cartel leader is also the suspected mastermind behind the murders of 72 migrants found on a ranch in San Fernando.
Mexico s president announced via Twitter the capture Sunday evening, saying, He was wanted because he s the Zeta leader behind the San Fernando massacre.
He s also suspected of ordering the murders of 200 people, mostly migrants traveling through Tamaulipas, whose bodies were found in a mass grave in the border state.
At a press conference, a Navy spokesman said Squirrel started his criminal career as a lookout, or halcon, for the Zetas.
He rose through the ranks to become a hit man and then third in command of the violent cartel by winning the trust of Miguel Trevino, the Zeta leader known as 40, who is in charge of lucrative smuggling route that cuts through Nuevo Laredo to Texas.
Squirrel is suspected of freeing 132 inmates from a prison in the border city Piedras Negras onSept. 18 because the cartel needed manpower to fight a bloody turf war in Nuevo Laredo.
Mexican Marines finally cornered and captured Squirrel in his hometown Nuevo Laredo on Saturday evening.
