Tulsa Apartment Murders Update: Four women all died from a gunshot wound to the head, medical examiner says
The office noted, however, that full autopsy reports are still pending for 23-year-old twin sisters Rebeika Powell and Kayetie Melchor, 33-year-old Misty Nunley and 55-year-old Julie Jackson.
Investigators have not said how the women all knew each other or why they may have been targeted.
According to court records, police have identified a man who "at a minimum" witnessed the killings at the apartment. That man, who has not been charged or arrested in the quadruple homicide, is being held on unrelated charges in the Tulsa County jail.
A judge increased bond for the man from $11,000 to $250,000.
