CNN: US Navy punishes more than 20 sailors over fire that destroyed warship

"The most serious actions focused on the leadership of the warship and the fire response team. The ship's former commanding officer, Capt. Gregory Scott Thoroman, and former executive officer, Capt. Michael Ray, received punitive letters of reprimand and forfeiture of pay. The former command master chief, Jose Hernandez, received a punitive letter of reprimand.

The Consolidated Disposition Authority, which decides upon punishments, was led by Admiral Samuel Paparo, the commander of US Pacific Fleet.

Vice Admiral Richard Brown, the retired officer who was the commander of US Pacific Fleet at the time, received a Secretarial Letter of Censure from Navy Secretary Carlos Del Toro."
