CHULA VISTA, Calif. -- The hunt is under way for whoever was responsible for the death of a Border Patrol agent in Southern California.
Federal investigators are combing hospitals along the U.S.-Mexico border for at least two suspects who may have been injured in the gunfire that killed agent Robert Rosas on Thursday night.
Rosas was responding alone to a suspected border incursion near Campo in southeastern San Diego County.
The FBI says law enforcement agencies are pursuing "a number of leads" in the United States and in Mexico, but that no one has been arrested or charged.
The Los Angeles Times reports that police in Tecate, Mexico, said Friday they had arrested an injured man walking near the crime scene with a Border Patrol-issued weapon shortly after the shooting.
No comment yet from the FBI.
