New video footage released Wednesday shows the final moments of a deadly confrontation between police and a 19-year-old, unarmed Fresno man on June 25.

Warning: Video may be considered disturbing.

Police Chief Jerry Dyer said officers believed Dylan Noble was about to shoot them during the encounter, learning only after the fatal shots were fired that Noble was not armed, The Fresno Bee reported.

The Bee obtained the new video on Wednesday. It was shot by a witness from a distance of about 100 feet.

The 26 seconds of footage began with an officer commanding Noble, who already was on the ground beside his truck and injured by two previous gunshots, to “Get your hands up!” It’s unclear how Noble reacted, but police fired a third shot at him soon after making the demand. Officers continued giving orders for several more seconds before firing a fourth and final shot at Noble. Throughout the encounter, the trio of officers stood just a few feet from Noble.

Two officers fired the shots that hit Noble, Dyer told the Bee, and both were long-serving veterans of the force. Dyer said the officers were wearing body cameras that give a clearer picture of the entirety of the incident and he planned to release that footage once the investigation into the shooting was complete.

“I anticipate the criminal investigation will be completed by the end of August as there is a need to wait for all of the physical evidence to be analyzed either by the Department of Justice and/or the Coroner’s Office,” Dyer said.

Noble’s parents have asked for an outside organization to investigate. Dyer told The Bee he was open to an external review, however, one has not yet been initiated.

Officers initially stopped Dyer on June 25 while looking into a report of a man dressed in camouflage walking with a rifle. Dyer said Noble did not comply with officers’ orders and the police believed Noble was armed. At one point, Dyer said, Noble approached the officers “very rapidly” and placed his right hand behind his back, making the comment “I hate my (expletive) life.”

That’s when police fired on Noble, who had no criminal history.

“There was no firearm on this individual,” Dyer told The Bee. “There was no firearm found in the pickup.”
