Earlier today, a woman was shot and killed by metro police, after aiming a shotgun at officers. After an eight hour standoff. Police were called out to a home near las vegas boulevard and craig just before six am. A nineoneone caller told police she saw video of her friend trying to overdose on pills. Police say the women refused to leave her home, and crisis negotiators tried to talk to her. At one point, the woman came out with a handgun, police say she ran back inside, and came out with a shotgun and tried to shoot herself first. She raised the shotgun and pointed it at the officers nearby. At which time two of our swat snipers fired. The tactic medic was on scene and attempted to provide medical care. However the female was pronounced dead at the scene. Metro will release the names of the officers involved in two days. And the coroner will release the suspects name.
