Four Houston police officers were fired Thursday after a months-long investigation of a fatal shooting found that they were "objectively unreasonable" in discharging 21 rounds at a man in distress.

On April 21 at around 9 p.m., multiple officers responded to several 911 calls about a man who was running through highway traffic.

Officers approached Nicolas Chavez, 27, in a parking lot, where he was running while holding a metal object, police said. During a roughly 15-minute interaction, officers shot Chavez with stun guns and bean bags while attempting to "stop him from harming himself," Houston Police Chief Art Acevedo said in a video compilation of the body-camera footage that was also released Thursday.
