Kierin Guillemin, 27, of Dixon, New Mexico, was one of three people found dead on June 2, 2018. The three deaths were investigated together as a triple homicide.

Police identified John Powell as the lone suspect. He was arrested and later charged with three counts of first-degree murder and one count of aggravated burglary in connection with the scene. In 2020 a jury convicted Powell on all three first-degree murder counts and the aggravated burglary charge. The New Mexico Supreme Court affirmed those convictions on May 7, 2024.

No other suspects were identified or charged in the killings. If anyone knew Kierin, was in Dixon around June 2, 2018, or has information about the events that night, please share what you know.
