On the evening of the incident, the agent, an eight-year veteran, encountered a man who had jumped the first border fence and was holding a ladder near the second, 15-foot wall, according to Border Patrol accounts provided to the San Diego Police Department, which is leading the investigation.

The man appeared to throw a rock, prompting the agent, whose name has not been released, to fire a single shot, police say. Because the wounded man fled back to Mexico, U.S. authorities say they haven't been able to confirm his identity.

Mexican officials said Martinez was taken to a Tijuana hospital and died the next day. He was shot in the back from about 16 feet away, according to the Mexicans' preliminary investigation.

Amid the rhetoric, an unusual level of cooperation has developed between law enforcement officials in both countries.

On Thursday, Mexican federal authorities handed over two witnesses to state and U.S. federal authorities at the San Ysidro border crossing. The witnesses, one believed to be the dead man's brother, were immediately taken to where the incident occurred.

From the Colonia Libertad neighborhood of Tijuana, residents marveled at the incongruous site of so many black-suited, heavily armed men dirtying their leather shoes on the muddy, garbage-strewn hillsides.

"Everybody is really interested," said one 6-year-old boy outside his tar paper shack.

Since the shooting, Mexican law enforcement agencies have stepped up patrols to discourage crossings and have agreed to erect signs warning people that assaulting U.S. agents is against the law.
