Three women—86-year-old Margaret Oldroyd, 65-year-old Linda Dewey, and 34-year-old Natalie Graves—were killed in a triple homicide in Wayne County, Utah.

Dewey and Graves, aunt and niece, were found at a trailhead south of Torrey, while Oldroyd was discovered at her home in Lyman.

Investigators tracked the suspect, 22-year-old Ivin Miller from Iowa, across multiple states using license plate readers and a key fob GPS, ultimately apprehending him in Pagosa Springs, Colorado.

Court documents indicate Miller admitted to the killings, shooting Oldroyd in her home and Dewey and Graves at a trailhead, then dragging their bodies to conceal them, KUTV 2 News has reported.

He was indicted on three counts of aggravated murder and was scheduled for his first court appearance in Pagosa Springs, with authorities reporting no known connection between Miller and Wayne County beyond passing through.
