On the morning of Sunday, September 11, 2022, 56-year-old Tina Lanis was shot multiple times in the back and killed at her home on Glenwood Drive in Walled Lake, Michigan. The attack left her 25-year-old daughter critically injured; the daughter survived and was later reported stable. The family dog was also shot and killed.

Police say the shooter was Tina’s husband, 53-year-old Igor Lanis. He opened fire on responding officers with a shotgun after the couple’s daughter called 911 to report that her father had shot her and her mother. Officers and a deputy returned fire and fatally wounded Igor at the scene.

A younger daughter, who was not home during the shooting, told investigators her father had become increasingly consumed by QAnon conspiracy beliefs after the 2020 election and had grown more irritable and paranoid. That change in his behavior is described as a major factor in the violence. Anyone with information about the Lanis family or that night is asked to come forward.
