The cartel member suspected of shooting and killing Border Patrol agent Brian Terry in 2010 with a gun supplied by the U.S. government was arrested in Mexico Wednesday, senior law enforcement, Border Patrol, and congressional sources told Fox News. 

The suspect, Heraclio Osorio-Arellanes, was apprehended by a joint U.S.-Mexico law enforcement task force that included the Drug Enforcement Administration, U.S. Marshals and the Border Patrol Tactical Unit (BORTAC).

A $250,000 reward had been sought for information leading to the arrest of Osorio-Arellanes, who was captured at a ranch on the border of the Mexican states of Sinaloa and Chihuahua. U.S. authorities have said they will seek his extradition.

Terry was killed on Dec. 14, 2010 in a gunfight between Border Patrol agents and members of a five-man cartel “rip crew,” which regularly patrolled the desert along the U.S.-Mexico border looking for drug dealers to rob.
