Robert Rosas Jr. was gunned down in Campo -- a small town in rugged San Diego County. Now this crime has a possible local connection.
The FBI, U.S. immigration agents, and San Jose police were at O'Connor Hospital for hours. They won't say what led them to the hospital, but they did take some people into custody.
It was a murder in the desert that prompted a massive man hunt. Federal agents are looking everywhere for the ones responsible for killing Agent Rosas. He was chasing a group of illegal immigrants or drug smugglers in Campo Thursday night when he was separated from fellow agents and shot.
"Upon review of the evidence it appears at least one, if not more of the individuals responsible for this crime, may have been wounded themselves whether by gunshot or by other means," said FBI Agent Keith Slotter.
On Friday, federal agents converged upon O'Connor Hospital in San Jose.
"I've seen around 15 unmarked vehicles and police officers. I wasn't sure if they were state or local. I knew they were undercover and they were scouring the parking lot and so forth and they were being real cautious about who was coming in or out," said Jerry Garcia, a witness.
Early Friday afternoon a man and a woman were handcuffed and taken away by authorities. Then at around 7 p.m., a man was discharged to federal agents after being treated in the E.R. for unknown injuries.
San Jose Police confirm the FBI asked for their help in tracking down suspects who may have been involved in Agent Rosas' murder.
The FBI still says no one has been officially charged with the agent's death. There is a $100,000 reward.
