BUFFALO, N.Y. (AP) — The white man accused of killing 10 Black people at a Buffalo supermarket appeared briefly in court Thursday after a grand jury indicted him on a first-degree murder charge.

Assistant district attorney Gary Hackbush said the indictment of Payton Gendron, 18, was handed up Wednesday.

The massacre at the Tops supermarket was unsettling even in a nation that has become almost numb to mass shootings. All but two of the 13 of the people shot during the attack were Black. 

Gendron, wearing orange clothing and mask, was silent throughout the proceeding and sent back to jail. Someone shouted “Payton you’re a coward!” as he was led out.

Ten people were killed and three others wounded in the Saturday shooting at the Tops Friendly Market in a predominantly Black neighborhood of Buffalo. Authorities are continuing to investigate the possibility of hate crime and terrorism charges.
