A Snowflake man has pleaded guilty to killing a staffer at a southern Utah youth-rehabilitation facility. Officials say 18-year-old Clay Brewer of Snowflake, admitted Thursday that he beat 61-year-old Jimmy Woolsey to death with a piece of metal in 2016. Prosecutors say Brewer, who was 17 years old at the time, attacked Woolsey around a campfire and then beat another staffer’s hand and head while she tried to keep him out of a cabin where other campers were hiding. Brewer told police in an interview that he was suffering from drug withdrawals and started “freaking out.” Brewer’s attorney said in a statement that his client apologized to the victims and the community and discussed the dangers of opioid abuse in America.
