Mexico Nabs Zetas Drug Cartel Leader 'Z-42'

Mexican federal forces captured Zetas drug cartel leader Omar Trevino outside the northern industrial city of Monterrey on Wednesday, dealing a new blow to the feared gang.

The suspect known as "Z-42" was detained by federal police and soldiers in the suburb of San Pedro Garza Garcia, Nuevo Leon state, two federal officials said.

Trevino, 41, took the helm of the Zetas after his brother, Miguel Angel Trevino or "Z-40", was captured by marines in the northeastern state of Tamaulipas in July 2013.

The US State Department had offered a $5 million reward for information leading to Omar Trevino's arrest. Mexican authorities offered a $2 million bounty.

His arrest comes on the heels of another major coup for the government, the capture last Friday of Knights Templar leader Servando "La Tuta" Gomez.

The arrests give President Enrique Pena Nieto major victories over drug cartels amid public anger over his government's handling of security, particularly the investigation into the disappearance and alleged murder of 43 college students.

But analysts warn that capturing cartel leaders does not necessarily mean an end to drug trafficking or violence, and that it can create smaller, vicious splinter groups.

"With Omar Trevino, the last of the solid leaders within the Zetas is gone," Mike Vigil, a retired chief of international operations for the U.S. Drug Enforcement Administration, told AFP.

"With this I think that the Zetas are going to have a very large void in terms of leadership. The big problem here, though, is that if the Zetas splinter into other organizations, then that can lead to violence in terms of the internal competition," he said.

The northeastern state of Tamaulipas has endured a spasm of violence in recent weeks, partly blamed on internal feuds within the Gulf cartel, former allies of the Zetas.

The Zetas are considered one of the most violent criminal organizations in Mexico, accused of melting enemies in a barrel of "stew" and, for example, of slaughtering 72 migrants in August 2010.

The group, founded by former elite soldiers, was originally the armed enforcer of the Gulf Cartel until the two groups split, unleashing a wave of violence in northern Mexico.

The government dealt a first blow to the Zetas in 2012, when top leader Heriberto Lazcano was killed in a gunfight with troops. His body was stolen by gunmen who stormed into a funeral home hours later.

Like his brother, Omar Trevino is not himself a former soldier, but the siblings were able to rise through the ranks of the paramilitary cartel.

The U.S. government says Trevino is allegedly responsible for several abductions and murders in the border city of Nuevo Laredo between 2005 and 2006 and is a supplier of multi-kilogram loads of cocaine smuggled into the United States.

In 2010, Omar Trevino told an informant that he had killed more than 1,000 people while Miguel had killed 2,000, according to an affidavit filed in a U.S. court for a case involving another Trevino brother in Texas.

Omar Trevino is "not as feared as his brother but he was able to maintain control because they respected him, and they new that Miguel Trevino still exerted some influence over the Zetas even though he was in jail," Vigil said.
