Mark Allan McCallum
(WZZM) - Two Mason County children, missing since Thursday, have been found safe and unharmed in Florida.
The Mason County Sheriff's Department sent out the notification Sunday evening.
They say at 4:30pm, the two children, four year old Douglas and two year old Shelby McCallum were found in Key West.
Their father, 52-year-old Mark McCallum, is now in custody.
Deputies say McCallum failed to show up for a custody exchange Thursday. That's when the search started and a warrant was issued for his arrest.
The children's parents were due in court Friday for a custody hearing.
The children's mother says this isn't the first time Mark has violated the court's visitation order.
Last November he took the children to Arizona without telling anyone.
Right now, there's no word on when McCallum will be returned to Michigan.
