All avenues are being explored in the ongoing search for two young missing children in Nova Scotia, according to police.

The Pictou County District RCMP provided an update Tuesday on the search for six-year-old Lilly and four-year-old Jack Sullivan.

It’s believed the siblings wandered away from their home on Gairloch Road in the rural community of Lansdowne Station, N.S., the morning of May 2.

The extensive search for the children involved up to 160 volunteer searchers, tens of thousands of search hours, and covered 5.5 square kilometres of heavily wooded and rural terrain. The search was scaled back last Wednesday, with police saying there was little chance the children were still alive.

“We have officers from multiple disciplines dedicated to finding Lilly and Jack, including highly trained RCMP major crime and forensic investigators,” said Staff Sgt. Curtis MacKinnon in a news release from the force.

Police say they have received more than 180 tips from the public and are following up on them.

They say they have interviewed 35 people as part of the investigation, including community members and “those closest” to the children.

The RCMP confirmed its Underwater Recovery Team searched bodies of water around Lansdowne Station last Thursday and Friday, but no evidence was found.

“We continue to work day and night on this file,” said MacKinnon. “Like all Nova Scotians, we want answers, and we want to know what happened to these children.”

Police continue to ask anyone with information on Lilly and Jack’s whereabouts to call the Pictou County District RCMP at 902-485-4333 or Crime Stoppers at 1-800-222-TIPS (8477).
