Mexican authorities said Friday that they apprehended Joe Luis Saenz, one of the FBI's Ten Most Wanted Fugitives.

The FBI posted a reward of $100,000 for information leading to Saenz's capture, Mexico's Public Safety Secretariat said.

Saenz was detained Thursday in the western city of Guadalajara following a joint investigation by Mexican Federal Police and the FBI, according to the official statement.

Thought to be 36 or 37, Saenz is wanted for offenses going back to July 1998, when he alleged killed two members of a rival gang in Los Angeles. Within days of the double-murder, he purportedly abducted, raped and killed a former girlfriend.

U.S. authorities also suspect Saenz in an October 2008 killing in Los Angeles and he faces charges for car theft, drug possession and parole violations.

The FBI said the Los Angeles-born Saenz traveled often between the United States and Mexico and that he was probably working for a Mexican drug cartel.

Saenz will be handed over to U.S. authorities later Friday, the Mexican government said. EFE
