The 14-year-old son of an Immigration and Customs Enforcement agent was arrested Thursday morning after the agent’s shooting death Wednesday night in a Carson, Calif., home.

Authorities responded to a 911 call at about 9 p.m. in the California town. The caller told dispatchers his father had been shot.

“We do believe (the son) made the 911 call,” said Lt. Holly Francisco.

The agent was pronounced dead at the scene.

He was around age 40, the Long Beach Press-Telegram reported. He was involved in ICE’s Homeland Security investigations, according to an ICE statement. ICE is part of the Department of Homeland security.

A preliminary investigation indicated the fatal round was fired from outside the home and through a window, investigators said. The agent’s service weapon was used in the shooting, according to investigators.

“This is a difficult time for ICE, especially for the family and loved ones of the agent. Please keep them in your thoughts and prayers,” ICE Director John Morton said in a statement.
