Ogden woman is charged with murdering boyfriend in deadly 2018 fire

Local News

OGDEN (ABC4 News) – A year-old arson investigation is now a homicide case after prosecutors say a May 1st, 2018 fire at the Towne Apartments on Adams Avenue was murder.

According to these charging documents, it was a perfect storm of methamphetamine use and mental illness that led to 57-year-old Kristilynn Thompson starting a fire that killed her live-in boyfriend 66-year-old, Dennis Singleton. Residents there still talk about what happened that day inside Unit 41.

Randolph Gardner was getting ready for work around 11 a.m.

“All of the sudden just bam,” Gardner told ABC4 News. “I run to my window looked out and fire was jumping out of this thing out of her apartment and stuff. It was crazy you know downright crazy.”

Prosecutors say the fire was no accident. They claim that Thompson admitted to starting it by kicking out a front window then reaching in and igniting a blanket after Singleton locked her out.

“Someone said ‘Her boyfriend’s in there’. I said ‘What?’,” Gardner said. “So that’s when we just start breaking stuff out trying to get in and the fume and the fire was so bad. You couldn’t even. You had to stand way back away from the door because that was blazin’ out so hard.”

Witnesses reported that as firefighters attempted to put out the blaze, Thompson said “there’s a pedophile in there” and “let him burn”. 

Singleton suffered smoke inhalation and was taken to the hospital where he died four days later. 

Thompson was admitted to the Utah State Hospital in Provo for treatment of mental health issues. Randolph Gardner calls it “a tragedy”.

“She was a nice lady,” he said. “But we all really knew she had mentally ill kinda problems you know.”

Ms. Thompson is also charged with possession of drug paraphernalia. In the past seven years, she pleaded guilty to assault, drug and DUI charges.

Thompson remains in the State Hospital. Her next court date is scheduled for June 6.
