LUDINGTON – Four-year-old Douglas McCallum and his sister, Shelby, 2, are reported missing in what the Mason County Sheriff’s Office is calling a parental kidnapping case. 

Their father, Mark McCallum, 52, of Hamlin Township did not show up for a custody exchange Thursday, which is when the sheriff’s office was called to investigate. Both parents are reported to live in Ludington.

Mark McCallum may be driving either a dark green 1995 Dodge pickup truck with Michigan license plate DALE12 or a dark blue 2005 Chevrolet Malibu with Michigan license plate 1CDX85.

He has family ties in the Grand Rapids area and in Arizona, police said in a news release.

Authorities have not yet released pictures of the kids or their father, or have issued an Amber Alert.

You are asked to call Mason/Ocean Central Dispatch at either 911 or 231.869.5858 or the Mason County Sheriff’s Office at 231.843.3475 if you can assist the investigation.
