Utah man dies of injuries suffered when his girlfriend allegedly started a fire at their apartment

Police identified a man Tuesday who died from injuries he suffered in an Ogden house fire, which his girlfriend allegedly started after an argument.

Three days after the May 1 fire at 2638 Adams Ave. critically injured 66-year-old Dennis Singleton, he was removed from life support and died, according to a news release from the Ogden Police Department.

Singleton lived at the apartment with his 56-year-old girlfriend, Kristilynn Thompson, who was arrested and charged with aggravated arson, a first-degree felony, according to police.

Ogden police Lt. Tim Scott said that before the fire, officers had been to the apartment on service calls for multiple domestic violence incidents involving Thompson and Singleton.

Scott said police believe that on the day of the fire, Singleton and Thompson were involved in a domestic quarrel and that Thompson started the fire at the apartment.

On May 1, firefighters and police were called to the complex at 1:18 p.m., where they began to evacuate the complex and found Singleton injured in one of the apartments.

The blaze affected six of the three-story building’s 18 units. Two Ogden police officers who tried unsuccessfully to rescue Singleton were treated for smoke inhalation.

Neighbors at the scene pointed police to Thompson, and police arrested her, according to a probable cause statement. She told officers she’d intentionally started the fire after Singleton had locked her out of the apartment.

Witnesses at the scene told police they’d seen Thompson kick in the window of the apartment, and then the fire began.

Singleton was in the apartment at the time and did not come out until fire officials extracted him. He was taken to Intermountain Medical Center in Murray, where he later died.

Scott said that while he can’t speak for prosecutors, police investigators are updating them with information that Singleton has died, which could possibly mean charges would be updated to reflect a homicide.

Thompson is being held at the Weber County jail in lieu of $22,000 cash-only. She is scheduled to appear in 2nd District Court on Thursday.
