A Minnesota man who murdered a woman decades ago was caught after he wiped his face with a hot dog napkin during a hockey game and was convicted of the killing last week. 

A jury convicted Jerry Westrom, 56, on Aug. 25 of first-degree premeditated murder and second-degree murder in the death of Jeanne Childs after a few hours of deliberation. 

Westrom was arrested 25 years after the June 1993 killing of Childs, who was found stabbed to death inside her apartment. 

"My condolences go out to the victim and her family. They have had to live without justice for her brutal murder for nearly three decades," Hennepin County Attorney Mike Freeman said in a statement. "I hope this brings some closure to them. Today’s guilty verdicts show that we will pursue convictions for serious crimes, even if it takes years to gather the evidence."

Westrom was arrested in 2019 after investigators retrieved a napkin he discarded during his daughter's hockey game. He was eating a hot dog and wiped his face with it. 

Westrom, who denies involvement in the murder, got on to the radar of investigators after they took advantage of advances in DNA technology in 2015 to take another look at the unsolved murder.
