The search for Lilly and Jack Sullivan will continue in Nova Scotia.

RCMP say ground search efforts are planned for Saturday in Landsdowne Station, Pictou County, in an effort to advance investigation and locate the missing four and six year old’s.

Specific areas around Gairloch Road and a nearby pipeline trail will be focused on, that’s where a boot print was previously located.

RCMP ask the public to avoid the search area.

They say any future searches will be determined based on the investigation.

It’s been four weeks exactly since the children went missing from their home in Landsdowne Station.
