Authorities say 32-year-old James Poore and 39-year-old Cedric Poore lived in the same apartment complex where the women were found. Officers wouldn't disclose a motive for the Jan. 7 killings, saying the investigation continues.

The brothers have not yet been formally charged.

On Jan. 7 twin sisters Rebeika Powell and Kayetie Powell-Melchor, 23; Misty Nunley, 33, and Julie Jackson, 55 were found murdered inside an apartment at the Fairmont Terrace Apartments in Tulsa. Police say each woman was shot. A 3-year-old boy also found inside the apartment was unharmed.

Investigators believe the killings occurred during the daytime because someone had heard from one of the victims a few hours before the bodies were found at midday.

CBS affiliate KOTV reports Cedric Poore has been in the Tulsa County jail on a traffic violation since January 14, and James Poore was arrested Wednesday morning. Department of Corrections records show James Poore has been previously incarcerated for robbery with a firearm.

Police have confirmed that the four women's deaths were not gang-related, KOTV reports.

The station says more arrests may be made in the case.
