New video and audio show how a Glendale pawn shop worker may have saved a woman’s life by calling 911 after the woman silently asked for help in May. The employee told dispatchers a woman inside the Glendale pawn shop mouthed “call 911” after her boyfriend allegedly became aggressive. Police say the suspect, Darren Howard, was trying to get the woman to buy a gun before officers arrived. Bodycam video shows officers entering the shop and ordering Howard to let the woman go as the encounter escalated. Police say Howard took her hostage with a knife, and officers used a Taser before another officer opened fire. Howard survived, and police say everyone involved made it out alive.
