After Nevada prison brawl kills 3 inmates, 20 people are charged

Nevada prosecutors say 20 people have been charged in connection with a brawl at a maximum-security prison in eastern Nevada last year in which three inmates were killed and others were injured.

The Nevada Attorney General's Office said this week the final arrest in the investigation was made on March 5.

Prisoners Anthony Williams, 41, Connor Brown, 22, and Zacharia Luz, 42, were killed in the July 30 fight at Ely State Prison. No officers were injured. Authorities say the charges in the case include first-degree murder and attempted murder with use of a deadly weapon with intent to promote or assist a criminal gang. It's not clear how many of the 20 defendants face those charges.
