DAYTON, Ohio (AP) — A grand jury has indicted an Ohio man accused of fatally shooting three people including his former girlfriend.

Montgomery County Prosecutor Mat Heck says the charges against 61-year-old Muhammad S. Ali carry the possibility of a death sentence if Ali is convicted.

Authorities say Ali took a gun to a Dayton home in August 2016 and killed his former girlfriend 53-year-old Tammy Cox; her son, 25-year-old Michael Cox; and 74-year-old Jasper Taylor, who was in the house at the time.

Records show Ali had been hearing voices when he was at a behavioral health care facility the day of the shootings.

The charges against Ali include aggravated murder, felonious assault, aggravated burglary and kidnapping. A message seeking comment was left with his lawyer.

Ali is scheduled for arraignment Tuesday morning.
