An Austin police officer shot and killed a man in north Austin early Monday morning after police witnessed the man stabbing a woman inside an apartment complex unit.

The Austin Police Department received a call shortly after 1:30 a.m. about a disturbance at 12501 Tech Ridge Blvd., interim Chief of Police Robin Henderson said in a news briefing. That address belongs to the San Paloma Apartments complex, though police didn’t specify which apartment complex the shooting occurred at in the briefing.

The caller told police they could hear neighbors arguing, glass shattering and things being thrown around. They also said the argument appeared to be between a man and a woman, with the man yelling and the woman shouting for help.

Police arrived at the scene around 1:45 a.m. and were flagged down by a woman, who showed them the unit where the disturbance was, Henderson said. Officers attempted to make contact with the unit’s residents, but when they were unsuccessful, they forced entry through the front door. At that point, officers located another door within the unit, forced entry and saw a man on top of a woman, stabbing her repeatedly.
