Mary Rose Carter Indicted for Intentional Murder

May 22, 2017

(ANCHORAGE, Alaska) Today, 32 year-old Mary Rose Carter was indicted for causing the death of 57 year old Gregg Niwa on May 9, 2017 at Niwa’s Tudor Area residence in Anchorage. The grand jury indicted Carter for murder in the first and second degree.

At approximately 2:24 p.m., on May 9, 2017, the Anchorage Police Department responded to a 911 call from a male who reported a deceased male in his residence. Officers responded and found Gregg Niwa deceased on the floor near the entrance to the residence. Detectives identified Carter as a suspect after she was described by Niwa’s roommate. Carter was arrested by the Anchorage Police on May 10, 2017. Carter is being held on bail of $500,000 and a court-approved third party custodian.

If convicted at trial, Carter faces a sentence of 30 to 99 years in prison for the murder in the first degree. A defendant’s sentence is determined by the judge who must consider the circumstances of the offense, the impact on the victim(s) and the community, and the potential for rehabilitation of the defendant. The charges in the indictment are only allegations and are not evidence of guilt. The defendant is presumed innocent and is entitled to a fair trial at which the prosecution must prove his guilt beyond a reasonable doubt.
