In a quiet Midvale, Utah neighborhood, the life of 65-year-old Eilleen Lyon came to a tragic end in what police have described as a murder-suicide. On the morning of Tuesday, September 23, 2025, officers from the Unified Police Department arrived at the home Lyon shared with her 63-year-old husband, Terry Lyon, on Jefferson Street to conduct a welfare check after one of them failed to show up for work.
Upon their arrival, police found the house secured, with doors and windows locked.
After repeated, unanswered phone calls and speaking with concerned neighbors and co-workers, officers obtained a key to enter the residence. Inside, they made the grim discovery of Eilleen and Terry Lyon, both deceased. Investigators believe that Terry Lyon shot and killed his wife before turning the gun on himself. A preliminary investigation revealed that Eilleen Lyon had sustained a gunshot wound, while Terry Lyon appeared to have died from a self-inflicted gunshot wound.
The news shocked those who knew the couple, with a next-door neighbor describing them as loving toward each other. The family also expressed their disbelief, stating that the couple had a very loving and close relationship and that they may never know why this tragedy occurred. Police confirmed that there was no known history of domestic violence at the residence. An obituary described Eilleen as a sweet, caring, and generous person who was loved by her friends and family. The investigation into the deaths is ongoing, with authorities working with the medical examiner's office to determine precisely when the couple died.
