The footage comes from a body-worn camera belonging to one of the two officers involved in the April 28 shooting as well as from the surveillance camera of a nearby business. The shooting killed Derrick Padilla, 29, of Los Angeles, who was wanted by the Los Angeles Police Department in connection with a homicide investigation. Padilla allegedly fired a handgun at Simi Valley police before he was shot and killed by two officers who returned fire: Senior Officer David Maupin, a 17-year law enforcement veteran who began working for the Simi department in 2016, and Officer Daniel Stradling, a 10-year veteran who joined the agency in 2015. "We are releasing this information to continue our commitment to transparency with our community to provide you with a better understanding of this event," Livingstone said at the video's start. Simi Valley police had been informed by the LAPD earlier that day about Padilla, a parolee wanted on suspicion of murder, possibly being in the city, Livingstone said. Officers were provided with a physical description of Padilla, but not a location. At one point, officers found a vehicle associated with Padilla abandoned in Simi Valley, Livingstone said. Later, LAPD officials contacted Simi police saying Padilla had been spotted at a local 7-Eleven. Surveillance footage confirmed Padilla had been at the convenience store and an updated description was broadcast to all patrol vehicles. At 8:04 p.m., minutes after the updated broadcast, Padilla was spotted walking northbound on First Street toward East Los Angeles Avenue. After Livingstone's introduction, the first of three video clips of starts. The footage shows a scene that quickly erupted with gunfire when officers pulled up in patrol vehicles. The first clip shows surveillance camera footage from a nearby car wash where the shooting took place. Padilla can be seen walking into the upper left corner of the frame along a sidewalk. After multiple police cars arrive, he shoots a handgun at police and runs partway across pathe parking lot before collapsing. The images show what appear to be muzzle flashes from Padilla's gun as he shoots toward officers, at times partially turned, while he runs from them across the empty lot. Livingstone said Padilla's gunfire hit both patrol vehicles. The police video included photos of the damaged cars. Neither officer was injured by Padilla's gunfire. The surveillance footage included audio overlay from dispatchers and Simi police radio. The audio was not recorded with the video but was edited together to sync up with the footage, according to police. Due to the Simi Valley Police Department encrypting its radio traffic in 2020, both the audio and video were newly released to the public. "Shots fired, shots fired, officers are OK, suspect is down in the parking lot," Stradling can be heard saying into the radio. "He has a gun to his right. We are facing northbound. He is down in the parking lot of the car wash." The second clip shows footage recorded by Stradling's body-worn camera. The footage shows Stradling driving his car, lowering the driver's side window, pulling a U-turn and exiting the car with his firearm. Stradling then radios police about the shooting. "The camera may capture things the officer cannot see or hear," Livingstone said during his narration. "Conversely, the officer may see or hear things not captured in the recording scope of the camera's view." The body-worn camera footage includes no audio until Stradling taps the camera to activate it. Livingstone attributes the lack of sound to a 30-second buffer recorded prior to the camera's activation. "Because this event happened so quickly by Padilla's immediate attack on the officers, body-worn video activation was delayed," Livingstone said. The investigation into the fatal use of force remains ongoing. Both officers remained on paid administrative leave as of Wednesday, according to Cmdr. Ritchie Lew, a department spokesman. Two investigations routinely occur after an officer-involved shooting. One is an internal investigation to determine if officers' actions were aligned with department protocol. The second will determine whether the shooting was lawful, conducted by the Simi Valley police department's major crimes unit and the Ventura County District Attorney's Office. The DA's Office also publishes public reports on all fatal officer-involved shooting investigations in Ventura County. "These investigations require significant personnel hours to interview all witnesses, view video footage and analyze various types of physical evidence," Livingstone said.
