Middleton declined to elaborate further on the state of the victim's body and said positive identification will be completed using dental records.
She added that authorities have yet to determine a possible motive for the apparent murder-suicide, which she described as "certainly violent." Authorities have not found a suicide note or a feasible explanation for it.
