Officer Mohamed Noor turned himself in on Tuesday after a warrant was issued for his arrest in the death of Justine Ruszczyk Damond. Damond was shot July 15, minutes after she called 911 to report a possible sexual assault in the alley behind her home.

The 40-year-old life coach was engaged to be married.

Hennepin County Attorney Mike Freeman was scheduled to discuss charges in the case at a 2:30 p.m. news conference.

Noor has not talked publicly about the case and declined to be interviewed by state investigators.

Jail records show he’s being held on $500,000 bail.
