Original Article Mar 2, 8:58 PM EST Agent says he "messed up" in not reporting 2005 shooting By ALICIA A. CALDWELL Associated Press Writer EL PASO, Texas (AP) -- A U.S. Border Patrol agent accused of wounding a suspected drug smuggler and then trying to cover up the crime testified Thursday that he made a mistake by not reporting the shooting. "I just messed up," Agent Ignacio Ramos told a jury in federal court Thursday. "I was just worried about a lot of other things. I was full of adrenaline ... I was worried about a lot of other things." Ramos and Agent Jose Alonso Compean are accused of shooting and wounding a Mexican national and not reporting it. When questioned by a prosecutor, Ramos testified he didn't see any physical confrontation between Osvlado Aldrete Davila and Compean but assumed there had been since he found Compean on the ground after hearing several shots fired. Ramos said he didn't stop to help Compean, who he initially feared had been shot, before chasing Aldrete on foot and firing a single shot because he was concerned that Aldrete was still a threat. "If I stop to help him, I'm leaving myself vulnerable ... that means two agents are down," Ramos said. "I can't take care of that agent if the threat harms me." After repeated questions from Assistant U.S. Attorney Debra Kanof, Ramos also acknowledged that he never used his two-way radio to report that shots were fired or that an officer was down. The Feb. 17, 2005, shooting was first discovered after Aldrete's mother reported it to the mother-in-law of an Arizona Border Patrol agent. Ramos and Compean, who each face about a dozen federal charges including assault with intent to commit murder, have denied any wrongdoing. Investigators said both men tried to cover up the shooting by not reporting it and Compean picked up several spent bullet casings after the incident. Testimony is expected to continue Friday.
