Southern California Edison shooting
2011 mass shooting in Irwindale, California, U.S.

On December 16, 2011, a mass shooting occurred inside a Southern California Edison office building in Irwindale, California. The gunman, Andre Turner, killed two employees and wounded two others before committing suicide.
Shooting
Andre Turner, 48, arrived at an office building that primarily houses information technology employees, at his usual work time in the morning. He showed no signs of strange behavior prior to the attack and people weren't even aware of the shooting unfolding. At 1:30 pm, Turner took out a handgun in an office building and shot four people. A relative of an eyewitness claimed that the eyewitness saw the gunman walk in to a room and told a manager he was going to shoot him before the gunman opened fire.
Investigators told reporters that Turner reportedly walked around the building during the shooting and talked to other employees who were unaware that he was the shooter, with many employees also unaware that there was a shooting at all. Other employees took action to protect themselves by pilling equipment in front of doors, and hiding in offices.
Victims
Two employees died: Henry Serrano, 56, of Walnut, and Robert Lindsay, 53, of Chino Hills, who were both supervisors and worked at the facility for at least twenty years. Angela Alvarez, 46, was critically wounded and Abhay Pimpale, 38, received a gun shot to his thigh.
