Manitoba RCMP are asking for the public's assistance in locating three missing children.

12-year-old Leon, 11-year-old Christopher and nine-year-old Thomas were first reported missing in December 2023 from Durham, Ontario.

On Sunday, the children were located at the Boissevain Port of Entry.

The kids were taken into care and their mother, 55-year-old Astrid Schiller, was arrested as a result of an outstanding Warrant of Arrest for Child Abduction from Durham Regional Police.

She was later released, as the warrant was not extended to Manitoba.

In the early morning hours of Monday, RCMP received a report that the kids were no longer in care at a residence in Forrest, Manitoba, and were missing.

Mounties believe the kids are with their mother.

She is believed to be driving a white 2018 Mercedes GLC with British Columbia license plate SJ9 75W.

Anyone with information on the Curr whereabouts of these children is asked to contact their local police service, 911 or Blue Hills RCMP at 204-726-7522.
