A Pasadena, California police officer is fired or faces disciplinary action after a colleague shoots him during an incident described by authorities as “horseplay” in a department parking lot, according to multiple reports. The Pasadena Police Department releases video footage showing what preceded the shooting and the moment the officer is shot, with the department and police chief describing the event as an alleged firearms-safety failure involving two officers in a vehicle area.

The Los Angeles Times reports the police chief says the department has released the video and that the incident is under investigation, and it later reports that fresh evidence and a witness with additional information lead to a new probe. Fox News similarly describes the video as showing the officers during the incident, including a moment where one officer points a gun toward the other.

SFGate reports that footage released by the Pasadena Police Department shows details leading up to the shooting. Across the outlets, the common elements are a cop-on-cop shooting in a Pasadena police parking lot, the use of released video, and an investigation that is expanded after additional information.
