Why this unique red dust could be a crucial clue in cold case of missing Bismarck woman Shelly Julson

'Clinker' found on the engine block of Michele 'Shelly' Julson's abandoned car in 1994 may be linked to an early sighting in rural Burleigh County, North Dakota, the Dakota Spotlight true crime podcast reports.

When Michele Julson disappeared from Bismarck on August 2, 1994, law enforcement didn't exactly have an abundance of clues to follow up on.

The most encouraging development occured six days later when her car was found parked at a local hotel—the Comfort Inn. They dusted for fingerprints without results but weeks later, when the blue Ford Thunderbird was returned to her father Wes Julson, he spotted a potential clue: clinker dust under the hood.

Listen to Episode Number 10 — Follow the Red Dirt Road

Clinker—commonly referred to as "scoria"—can be found throughout western North Dakota and is occasionally used as a substitute for gravel on country roads.


In episode 10 of Dakota Spotlight, working off of new information from both a retired sheriff's deputy and a local geologist, host James Wolner asks the question: Could the clinker dust be related to an early (and almost forgotten) reported sighting of Michele's car in rural Burleigh County?

That is mostly farmland and pasture land up there ... I would say there would be plenty of places that something could be hidden.
Ray Dingeman, retired Burleigh County sheriff's deputy

Retired sheriff's deputy Ray Dingeman patrolled Burleigh County's rural roads for 25 years. Having recently listened to Dakota Spotlight's reporting on missing Shelly Julson, Dingeman contacted host James Wolner with pertinent information about a specific, remote area of the county

Ray Dingeman knows rural Burleigh County roads very well. Today he teaches criminal justice at United Tribes Technical College in Bismarck but previously he worked as a sheriff's deputy when he patrolled throughout the county for 25 years. After listening to Dakota Spotlight season 7 and learning that red clinker dust had been found on the engine block of Julson's car, Dingeman contacted Wolner to share his recollections and knowledge of rural Burleigh County.

Dingeman noted that, in 1994, some rural roads in the northwestern section of the county were covered with clinker. He specifically pointed Wolner to an area near the town of Baldwin which lies just 12 miles north of what was Julson's place of employment: The Burnt Creek Club (now named "The Crossroads Tavern" at 1205 Northstar Dr. in Bismarck).

Dingeman says the remote and rural area in northwestern Burleigh County wouldn't be a bad place to try to hide something — such as a body.

"That is mostly farmland and pasture land up there ... I would say there would be plenty of places that something could be hidden," he said.

Dingeman's information prompted Wolner to re-examine the Julson cold-case file after he remembered reading a reference to a reported sighting of Julson's car near Baldwin.

And sure enough, there was.
