OSBI agents say after they interviewed Tanner Douglas Jenkinson they booked him on a complaint of murder in the first degree.
Agents say on January 16th, Jenkinson drove the shooting suspect, identified as 19-year-old Henry Jackson, to the 4500 block of South Preston Road in Tishomingo.
Agents say Jackson killed Marcus Cole Holt and kidnapped Holt's girlfriend and her two young children. Officials say Jackson then took the kidnapping victims to Ardmore where they were eventually released.
He was killed by law enforcement after they say he fired shots during a police chase.
