SALT LAKE CITY — A man who was paroled less than a year ago from the Utah State Prison after serving more than 40 years for killing a Utah Highway Patrol trooper has been arrested again.
Brian Keith Stack, 60, was booked into the Salt Lake County Jail on Thursday for investigation of enticing a minor, dealing in harmful materials to a minor, and sexual exploitation of a minor.
Stack shot and killed UHP trooper Ray Lynn Pierson on Nov. 7, 1978, after being pulled over on state Route 20 for a minor traffic violation. Pierson was unaware that Stack was a fugitive from Illinois and had just stolen gas in Cove Fort.
Stack was arrested following a chase during which he hit a police car set up as part of a blockade. A total of 87 bullet holes fired by officers were later counted in Stack's car, including 11 in the windshield. Amazingly, Stack survived with only minor injuries.
He eventually pleaded guilty to the equivalent of aggravated murder in exchange for prosecutors not seeking the death penalty. At the time he was sentenced, life in prison without the possibility of parole was not an option for Utah judges.
In February 2019, Stack went before the Utah Board of Pardons and Parole to plead his case for parole, which was later granted. He was released from the prison on Feb. 17, 2020.
Stack began chatting with an undercover officer posing as a 14-year-old girl on a social media app earlier this month on Jan. 2, according to a police affidavit.
"Brian continued the message conversation and eventually began to request sexual acts from the female," the affidavit states. "Brian requested nude photographs several times from the female and suggested he take nude pics of the female when they met."
Stack also sent his own explicit pictures, according to the affidavit. He arranged to meet the "girl" on Thursday in Salt Lake City. When he arrived he was arrested by police.
