Gene Seim, 67, was shot to death inside his Shelby Township home on July 9, 2026. An Air Force veteran and Utica resident, Seim’s death occurred during a domestic dispute that investigators say involved a family member. Police arrested his 38-year-old stepson, Trevin Beemer, at the scene.

Beemer was charged with first-degree premeditated murder and several other felonies, including assault with a dangerous weapon and multiple firearms offenses. A judge denied bond at arraignment and ordered a competency evaluation after Beemer told the court he had been on the wrong medication. Prosecutors say Beemer opened a gun case, took a firearm and shot Seim multiple times, and that he later tried to stop a witness from calling police.

If anyone knew Gene Seim or has information about what happened that night, please share what you know with investigators.
