Search efforts are continuing for two siblings who went missing earlier this month in Nova Scotia, Canada.

Royal Canadian Mounted Police (RCMP) said more than 115 volunteer searchers participated in Sunday’s search, which focused on areas around Gairloch Road in Lansdowne Station.

The Context

Lilly and Jack Sullivan went missing from their home on Gairloch Road on May 2. Officials transitioned from a full-scale search to searches in smaller, more specific areas on May 7.

The area where the children went missing contains “heavily wooded, rural terrain,” police said.

What To Know

Police said Lilly, 6, and Jack, 4, are believed to have wandered away from their home.

Lilly has shoulder-length light brown hair with bangs. She might be wearing a pink sweater, pink pants and pink boots.

Jack has short blondish hair. He is wearing blue dinosaur boots, but no other clothing description is available.

The children last attended Salt Springs Elementary on April 29. There was no school the next day, and they were kept home due to illness on May 1 and 2.

Police have identified 35 people to interview, The Chronicle Herald reported. The children’s stepfather, Daniel Martell, was questioned by police for four hours.

RCMP said the search has covered 5.5 square kilometers (2.1 square miles). On May8 and 9, the RCMP’s Underwater Recovery Team (URT) searched bodies of water near Lansdowne Station but did not uncover any evidence.

The case has resulted in social media speculation and online misinformation.

RCMP Public Information Officer Corporal Carly McCann previously confirmed to Newsweek that the children are still missing.

Lilly and Jack Sullivan: Map Shows Every Update in Search for Missing Kids

As the search for Lilly Sullivan, 6, and her younger brother Jack Sullivan, 4, enters its fourth week, the timeline and geography of the investigation continue to be painstakingly analyzed by law enforcement, journalists, and members of the public. The siblings disappeared from their rural home near Lansdowne Station, Pictou County, Nova Scotia, on May 2, triggering a massive, multi-agency search effort that has yet to uncover any trace of them.

A detailed map now outlines key locations, sightings, and search zones involved in the case, providing a clearer picture of the RCMP’s efforts—and underscoring the complexity of the terrain that has hampered the search.

Gairloch Road, Lansdowne Station – Last Known Location

The Sullivan children were reportedly last seen at their family home on Gairloch Road, a remote stretch surrounded by dense forest, wetlands, and rugged, undeveloped land. According to the original 911 call placed on May 2, the children had “wandered off” into the surrounding woods. This is where the initial ground search began, immediately involving local police, RCMP units, search and rescue teams, K9 units, and aerial support.

Search Perimeters and Grid Areas

In the first 72 hours, authorities created a wide grid pattern spanning multiple square kilometers around the home. Searchers worked outward in expanding circles, focusing first on trails, creeks, and logging roads. Drones with infrared cameras, helicopters, and underwater search equipment were deployed. Despite this effort, not a single footprint, item of clothing, or piece of physical evidence linked to the children was found.

Nearby Properties and Waterways

The map also indicates locations of neighboring properties that were visited and searched. Local ponds, marshy bogs, and parts of the East River St. Marys—an expansive waterway system nearby—were methodically swept by divers. Boats and sonar were used to search deeper areas, but again, nothing conclusive was recovered.

Tips and Reported Sightings

Several tips have emerged from residents in surrounding communities—places such as Merigomish, Eden Lake, and New Glasgow. Some reported seeing children matching the description of Lilly and Jack near gas stations or backroads. These tips were marked and followed up on by investigators, but none have been verified. The map now shows several “tip response” markers that trace the direction of reported sightings, though no patterns have emerged.

Shift from Search to Investigation

Around day 10, the RCMP shifted focus from an active wilderness search to a broader criminal investigation. Search command posts were dismantled, and more officers were reassigned to interviews, digital evidence collection, and reviewing timelines. The map’s legend marks this turning point clearly—showing a move away from purely terrain-based strategy to investigative work within the community and family circle.

Family Home Revisited by Investigators

The family residence has reportedly been revisited more than once by police. Forensic units conducted multiple sweeps of the home and surrounding structures, looking for any signs that could suggest foul play or an alternative timeline. The map marks this as a “key reexamination site,” showing the renewed focus on the immediate area around the house.

Community Searches and Volunteer Efforts

Local volunteers have organized their own search parties in areas not covered by official operations. These include walking power line trails, rural backroads, and old hunting cabins in the region. Volunteer-reported areas are now being added to a crowdsourced digital map, giving the public a chance to visualize where efforts have been duplicated or may need new attention.

Digital Forensics and Device Mapping

Investigators are believed to be analyzing cellphone data, internet usage, and possible GPS-related pings, although no official statement has confirmed what—if any—digital trace was available. The map includes placeholder icons where cellular towers in the area are located, suggesting one avenue investigators may be using to narrow down timelines or locations.

Why the Map Matters

Mapping every aspect of this search not only provides clarity on what has been done but also shows the immensity of the terrain and the challenge responders face. It also highlights a troubling reality: that after nearly a month, there’s been no hard evidence of where Lilly and Jack went or what happened to them.

The map serves as both a logistical tool and a visual representation of heartbreak. Each marker is a place where hope surged—or faded. Each path searched and pond dredged carries with it the weight of a community’s desperation and a family’s grief.

Authorities continue to urge anyone with information to come forward, no matter how insignificant it might seem. As one RCMP officer said, “All it takes is one small clue to change everything.”

In the meantime, the search map continues to grow—now not only a record of effort but a symbol of the unanswered question haunting Nova Scotia: Where are Lilly and Jack Sullivan?
