On February 13, 2015, 42-year-old Irene Deni Halverson was fatally shot while visiting a clean-and-sober house in Everett, Washington. She was described as an unintended victim who had no connection to the underlying dispute; two others were attacked that day — Kevin Odneal was killed and another woman was seriously injured. Halverson was a mother to two daughters and was remembered by family as caring and devoted to her children.

The shooter was 39-year-old Tye Fleischer, the manager of the residence. After the shootings he fled but later called 911 and admitted to the killings.

Fleischer was charged with aggravated first-degree murder and attempted first-degree murder; prosecutors said the attack was planned, while the defense argued self-defense. The jury convicted Fleischer of aggravated murder and attempted first-degree murder, and he received a mandatory sentence of life in prison without parole. Does anyone have memories of Deni or information about that night to share with the family or investigators?
