iStock/Thinkstock(LOS ANGELES) — Police released graphic body-cam footage on Tuesday in connection with a shooting in Los Angeles that left an armed suspect and a hostage dead last month.The video, recorded on June 16, showed Los Angeles Police Department (LAPD) officers as they responded to a call about a suspect — later identified as Guillermo Perez — who had reportedly stabbed his ex-girlfriend moments earlier, according to police.Responding officers arrived on the scene in Los Angeles’ Van Nuys area at around 1 p.m. to find Perez standing outside a church with a metal folding chair and a large kitchen knife in his hands, according to the footage.Perez approached the officers as soon as they exited their vehicles and ignored repeated commands to “drop the knife,” the footage showed. The officers said they fired “less lethal” beanbag rounds at him to de-escalate the situation, but he blocked the shots with the metal chair, according to police.The graphic video shows that, as the suspect runs away from the officers, he grabs an innocent woman — 49-year-old Elizabeth Tollison — taking her as a hostage before putting the knife to her neck.“Perez then pushed the woman in between himself and the officers, raised the serrated knife and pressed it against the woman’s neck,” the police department said in a statement Tuesday. “At this point, three officers fired their handguns at Perez, who was hit by the gunfire and fell to the ground.”“Tragically, Perez’s hostage was also struck by gunfire, collapsed and later died from this gunfire,” the statement adds.LAPD Chief Michel Moore said it had been 13 years since an officer’s gunfire had killed an innocent bystander or hostage.He said the department plans to implement a new training program and hopes to equip officers with other nonlethal weapons.“This was a tense situation that unfolded very quickly. It’s every officer’s worst nightmare,” Moore added.Copyright © 2018, ABC Radio. All rights reserved.
