Matthew Miller was 21 when he was found dead on March 5, 2021, among four decomposing bodies discovered inside a pickup truck in the parking garage of the Albuquerque International Sunport. He was from Grants, New Mexico; people who knew him described him as decent and fond of his pets and said he had endured several family deaths the year before and struggled with opioid addiction and health problems that limited his ability to work.

Also killed were Jennifer Lannon, 39, and Jesten Mata, 40, both described as friends of Miller’s from Grants, and 60-year-old Randal Apostalon of Albuquerque, who reportedly provided rides for money. Authorities focused on Jennifer Lannon’s ex-husband, 47-year-old Sean Lannon, who was arrested after a nationwide search and confessed to the killings, alleging motives that included an affair and accusations about photos; Grants police said there was no evidence supporting the claim about Miller.

The legal case against the suspect is ongoing. If anyone knew Matthew, his movements that day, or has information about his relationships in Grants, please come forward.
