The FBI says an immigration agent shot and injured another agent and was then killed by a third colleague in a federal building in Long Beach.
FBI Special Agent Steven Martinez says the shooting occurred at about 5:30 p.m. Thursday.
There were conflicting early reports about the number of people shot, with local authorities saying two were dead and one wounded, while ICE said one was dead and one wounded.
Martinez characterized the incident as a case of workplace violence involving two federal agents. He says one agent fired several rounds at another agent, wounding him. At that point, another agent intervened and additional rounds were fired, resulting in the death of the shooter.
