An evidence-suppression hearing that had been set for Friday in the John Montstream murder case was postponed until Sept. 27.
First Assistant District Attorney Timothy R. Lundquist said witnesses needed to conduct the hearing were unable to appear.
The session was to have been the first hearing on motions filed by John R. Parinello, the attorney for Michael Northrup, 28, of Caledonia. Northrup is charged with second-degree murder, conspiracy, and second-degree criminal possession of a weapon.
Northrup is accused of killing Montstream with a single shot to the head on June 23, 1998, and leaving his body in a minivan parked in a parking ramp in downtown Niagara Falls, where it was discovered a week later. Northrup was arrested Nov. 5.
The victim's wife, Annette Montstream, 40, of Clarkson, also is charged with murder and conspiracy for allegedly asking Northrup to kill her husband. Prosecutors said the two were having a platonic affair, but Montstream refused to divorce his wife.
