The individuals located dead on the scene of the homicide/suicide Sunday in the 10200 block of Co Rd 100S have been identified as Dianne Cook, 65 years of age, and Barri Cook, 61 years of age, both of Avon. The Cooks’ had been legally divorced since 2019; however, they were known to continue living together within the same residence.
The preliminary investigation indicates that there was some type of altercation in the home, and Dianne Cook was apparently shot multiple times by Barri Cook. Barri Cook subsequently died from what appears to be a self inflicted gunshot wound.
