Two inmates are suspected of killing a third inmate at a Clark County prison. Ralph E. Goodman, 39, died in an attack at High Desert State Prison about 30 miles north of Las Vegas. Goodman was being escorted by a prison guard to his cell when Jeremy Nuckles, 39, and Justin Mitthias Muncy, 32, charged across the yard towards Goodman and despite being pepper sprayed they attacked him, knocked him to the ground and stabbed him, the department said. The Clark County Coroner's Office will do an autopsy and the Inspector General's Office will review the incident.
