Buffalo mass shooter sentenced to life in prison

The man who opened fire at a Buffalo supermarket and killed 10 black people last year was sentenced to life in prison without the possibility of parole Wednesday after he pleaded guilty in November. 

Payton Gendron's hearing was interrupted for about 10 minutes after a man in the audience charged at him.

"There was nothing hasty or thoughtless about your conduct. There are no mitigating factors to be considered," Judge Susan Eagan said at the hearing, The Associated Press reported.

Gendron's guilty plea to murder and hate-motivated terrorism charges ensured that he would spend the rest of his life in prison. His admission of guilt is seen as a possible attempt to avoid the death penalty in a federal trial.
