Tulsa police have arrested a woman investigators say watched as a man was beaten to death then fed to hogs in Muskogee County.

Wednesday, the Tulsa Police Fugitive Warrants arrested Charletha Mack near 1200 North Sheridan in connection with the murder of Courtney Palmer.

Officers say Palmer witnessed a shooting and he was killed to keep him from talking.

Police said Mack was present at the time of Palmer’s torture and did nothing to intervene or assist.
