Katherine Holmberg, 41, was killed in her Chandler, Arizona home in the early hours of May 31, 2023, in what police described as a murder-suicide. Katherine was pregnant and expecting her first child, a daughter to be named Molly Blake Holmberg.

Shortly after 1:00 a.m. officers received an initial 911 call from an intoxicated, uncooperative man who would not give his address. Family members then called 911 identifying that man as Katherine’s 38-year-old husband, Kevin Holmberg, and saying they feared for her safety. Police surrounded the couple’s residence in the 3900 block of W. Monterey Street. Kevin exited the home armed shortly after 2:00 a.m. and shot himself in view of officers. Inside, officers found Katherine deceased from a gunshot wound believed to have been inflicted by her husband; investigators concluded no one else was present.

Anyone with information about Katherine, her family, or the events that night is asked to come forward.
