(CSi) Yorie Kahl, has been denied parole by the U.S. Parole Commission.

The, now, 63 year old Kahl and the now 69 year old Scott Faul, are serving life sentences for the shooting deaths of a U.S. marshal and deputy marshal outside Medina, North Dakota in 1983.

Known as “The Medina Shootout”, the shooting occurred when marshals attempted to arrest Yorie’s father, Gordon Kahl.

U.S. Marshal Ken Muir of Fargo and Deputy Marshal Robert Cheshire of Bismarck were killed in the shootout. Deputy Marshal James Hopson of Bismarck, Stutsman County Deputy Sheriff Brad Kapp and Medina Police Officer Steve Schnabel were also shot.

If Kahl was released on parole, he would be put on probation. He will be eligible for parole again in two years.
