ICE agent shot dead, teen son arrested CARSON, Calif., May 3 (UPI) -- California authorities arrested the 14-year-old son of a federal Immigration and Customs Enforcement agent who was shot to death, officials said Thursday. The agent, whose name was not reported, died Wednesday after a single shot was fired into his Carson home, hitting him in the head, the Los Angeles Times reported. Lt. Holly Francisco said the teen, whose name was not reported, allegedly fired the shot using his father's ICE-issued handgun from the family's back yard. Police have not determined a motive for the shooting, she told the Times. "This was a domestic violence incident," she said. The agent, 40, had been with ICE for four years. He is the second Los Angeles-area ICE agent to be killed by gunfire this year.
