The Anchorage Police Department says Mary Rose Carter has been arrested for the murder of Gregg Niwa. According to a release from the agency, on Monday Carter, 32, was at Niwa’s home, where they’d both been drinking. The two got into an argument, then Carter shot Niwa before stabbing him “several” times in the torso,” APD said.

“She ran from the home and did not contact police,” police wrote in a release.

Tuesday afternoon, Niwa’s roommate discovered his body.

Carter was picked up by police Wednesday. She was questioned, arrested, and then charged with first-and-second-degree murder.

According to Carter’s charging documents, Niwa’s roommate told police he met Carter about a month and a half ago and started drinking heavily with her. The roommate told police they’d go through a gallon of R&R per day and argued frequently.

The criminal complaint says when detectives found Carter, she explained she and Niwa were alone Monday night, after drinking heavily for two days straight, when they began to argue over “pregnancy concerns.” Carter told APD Niwa shot a handgun multiple times, then set it down and might have been going to get another gun. That’s when she picked it up and shot him, then got knives from the kitchen and stabbed him multiple times, “so he would not get up.”
