BUFFALO, N.Y. — The white man accused of killing 10 Black people in a racist attack on a Buffalo supermarket was indicted by a grand jury Wednesday on domestic terrorism and hate crime charges that would carry a mandatory life in prison sentence.

Payton Gendron will be arraigned Thursday on the new, 25-count indictment, building on a previous murder charge prepared in the hours after the May 14 shooting.

The 18-year-old has now also been charged with using a weapon while committing a felony and for the attempted murders of three people who were shot during the attack, but survived. Murder charges were filed for each of the victims including eight customers, the store security guard and a church deacon who drove shoppers to and from the store. 

Gendron has pleaded not guilty. The crime and number of victims was likely to guarantee a life sentence if Gendron is convicted.
