Tulsa homicide detectives on Friday told News On 6 they have located a person of interest and conducted an interview in connection with this week's quadruple homicide.
Police are not releasing the person's name or revealing what, if anything, the person told them. A source said investigators are following up on information and are continuing to look for others who might be involved.
On Monday about 12:30 p.m., four women were found murdered at the Fairmont Terrace Apartments, located on 60th Street and South Peoria Avenue in a crime-ridden stretch of South Tulsa.
A toddler was found unharmed in the apartment, with the bodies of Rebeika Powell, 23; Kayetie Powell-Melchor, 23; Misty Nunley, 33; and Julie Jackson, 55, tied up and shot to death.
Detectives have interviewed dozens of people about the case.
Earlier this week, police tracked a man to Kansas and questioned him about the murders. Authorities were quick to say Joseph Tillmon, 33, is not a suspect, but believed he knew one of the victims and may have had information that could aid the investigation.
Police said they have since ruled out Tillmon as a person of interest.
Jackson's service is scheduled for Monday at 11 a.m. at Shurden-Jackson Funeral Home in Okmulgee.
Services for Nunley are still pending.
