A memorial service originally scheduled for Sunday to remember James "Jimmy" McGregor has been postponed due to inclement weather, according to the Red Lodge church organizing the service.

"Due to winter weather conditions, Jimmy McGregor's memorial has been postponed," Church of the Rockies wrote in a post on its Facebook page Sunday. "We would like for everyone to have the opportunity to attend, so we will pray for better weather, and reschedule the service at a more appropriate time."

News broke late last month that McGregor's body had been found near a trailhead south of Red Lodge. Police believe he was killed and another Red Lodge resident, Thomas Schifferns, was arrested on suspicion of deliberate homicide in his death.

At this time, no date has been set for the rescheduled service, according to the post.

McGregor had been an active member of the Southern Baptist church since it opened its doors nearly four years ago, Church of the Rockies Pastor Lee Merck previously told the Gazette.

A winter storm warning remains in effect for south-central Montana and other portions of the state through Sunday night. Up to 5 inches of snow had already been reported in the Red Lodge area by early Sunday morning, according to the National Weather Service.
