By: Storme Jones OKLAHOMA CITY - The Oklahoma County District Attorney is requesting the acting state attorney general investigate an Oklahoma City police detective. District Attorney David Prater sent a letter to the attorney general’s office requesting they open an investigation into the conduct of investigator Bryn Carter after he recanted his findings in the police shooting of Bennie Edwards. In the letter obtained by News 9, Prater asked acting Oklahoma Attorney General Dawn Cash “to determine whether the conduct is a violation of Oklahoma Law." Earlier this year, the detective signed an affidavit alleging his fellow Oklahoma City police officer Clifford Holman "unnecessarily" shot at Benny Edwards' back three times and should be charged with first-degree manslaughter.
