TULSA – The convicted murder who is accused of operating a methamphetamine drug ring with a contraband cell phone, while incarcerated at an Oklahoma prison, was federally indicted on several drug related and conspiracy charges.

The 22-page indictment, unsealed on Thursday, Sept. 21 in the Northern Division of the United States District Court, lays out a plan of where Slint Tate, 35, used a contraband cell phone to enable buying and selling methamphetamine in northeast Oklahoma and other alleged criminal activity.

Also indicted are Robin Tracy Zumwalt, also known as Robin Tate; Rachael Georgia Danley, Ashton Chase Manicom, Jeremy Dallas Mann, Matthew Stroud and Todd Allen Pryer, also known as Todd Pryor. Court records show state criminal charges against them were dismissed on Wednesday, Sept. 27.

Delaware county District Attorney Kenny Wright has referred to the group of 28 defendants as the “Slint Tate Drug Ring,” saying it is responsible for moving at least five pounds of methamphetamine a week, with a street value approximately $250,000 to $1 million.

Of the defendants, 21 individuals have received suspended sentences, are in custody of the Department of Corrections, federal custody, probation or charges were dismissed, court records show.

In an earlier interview, Wright said Tate was not charged in state court, because he is already serving a life sentence.
