Pedro Guzman is an American citizen. He is also reportedly retarded. And his family is concerned about his safety. Guzman disappeared after he was arrested for misdemeanor trespassing. Sometime after that, officials with the Los Angeles County Sheriff's Department identified him as an illegal alien and turned him over to Immigration and Customs Enforcement, which deported him to Tijuana. Both agencies say they acted properly and blame the mistake on Guzman, who they say claimed to be from Mexico.
