UPDATE:

The individuals located dead on the scene of the homicide/suicide yesterday 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.  

Hendricks County Detectives along with the Hendricks County Coroner’s Office are continuing to investigate this incident.  Hendricks County Authorities are also asking for assistance from the community in identifying family members or legal next of kin for Barri Cook.  If you have any information that might help identify Barri Cook’s family or legal next of kin, you are asked to please contact the Hendricks County Coroner’s Office at (317) 718-2910.

Original Release:

The Hendricks County Sheriff's Department and coroner are handling a death investigation.

Just after 9 a.m. Saturday, deputies responded to the report of a welfare check in the 10200 block of Co Rd 100S.  It was reported to deputies, by a family member, that they were unable to reach a loved one at the residence and that the person had not reported to work in several days.  A family member made entry into the residence with the assistance of Hendricks County deputies and located two people deceased.

Deputies secured the scene and contacted investigators to respond.  As is routine procedure in these types of cases, a search warrant was obtained to further the investigation.  At this time the Hendricks County Sheriff’s Office can confirm that there are two people deceased in the home, a man and a woman.  Both are believed to be residents of the home in which they were located.
