Perry Woo is being called a hero for stopping the shooting spree at the Federal Building in Long Beach.

The two ICE agents shot were discussing the alleged shooter’s job performance when supervisory Special Agent Ezequiel Garcia, 45, reportedly turned his gun on his supervisor, Deputy Special Agent-In-Charge Kevin Kozak.

Woo intervened and fatally shot Garcia.

Kozak, 51, suffered six gunshot wounds to his legs, stomach and hands and was rushed to the hospital, where he is now alert and talking with family and friends, said Claude Arnold, special agent in charge for ICE/Homeland Security Investigations in Los Angeles. Kozak reported directly to Arnold.

“Agent Kozak is alive today because of the heroic actions of a third ICE supervisor,” Arnold said. “While that agent’s quick thinking saved Agent Kozak’s life, it also meant one of his colleagues died.”

The FBI is investigating the shooting, Arnold said, declining to further divulge details about the shooting. However, the Los Angeles Times reports that the shooting erupted during a discussion about Garcia’s job performance.
