Federal and local authorities say a man held in a Texas jail had nothing to do with the 2010 killing of a Border Patrol agent in Arizona. 

In an interview with Spanish language network Univision, a man identified as Gustavo Lozano Cruz takes responsibility for Brian Terry's death. 

Terry was mortally wounded in a firefight between agents and five men planning to rob marijuana smugglers. Two rifles found at the scene were linked to the botched federal investigation known as Fast and Furious. 

Lozano Cruz was arraigned Thursday on two counts of making a terroristic threat against Hidalgo County, Texas, Sheriff Lupe Trevino, who says he has no evidence Lozano Cruz was involved with Terry's killing. 

An FBI spokesman in Phoenix says the information in the report is inaccurate.
