A Montana man charged with killing another man by hitting him in the neck with a tomahawk has also pleaded not guilty to threatening a witness.

James Michael Parker pleaded not guilty Monday to the tampering charge.

He previously pleaded not guilty to deliberate homicide in the 2018 death of Lloyd Geaudry during a street brawl in Great Falls involving nearly a dozen people.

Prosecutors allege Parker threatened the witness, who was also in jail, after reading the police report on the case.

Parker's trial is set for Aug. 3.
