The disappearance of siblings Lilly Sullivan, 6, and Jack Sullivan, 4, from their rural home in Lansdowne Station, Nova Scotia, on May 2, 2025, has evolved into one of Canada’s most perplexing and heartbreaking missing persons cases. Reported missing by their mother, Malehya Brooks-Murray, the children were said to have wandered away from the family trailer on Gairloch Road, surrounded by dense woods, steep banks, and thick brush. Yet, months later—with extensive searches yielding no trace—the focus has shifted toward inconsistencies in the family’s accounts, particularly those of stepfather Daniel Martell, and a puzzling nighttime vehicle activity involving a white Nissan that neighbors insist they heard.

The siblings lived in a modest mobile home with Brooks-Murray, Martell (her common-law partner), their one-year-old daughter Meadow, and Martell’s mother, Janie Mackenzie, who resided in a separate trailer on the same property. The family had moved there about two years earlier. Lilly and Jack were described by Martell as possibly undiagnosed autistic and prone to wandering, a detail he emphasized in early interviews to explain how they might have slipped out unnoticed.

According to the official timeline, the children were last seen publicly on the afternoon of May 1, 2025, during a family outing to nearby New Glasgow. Surveillance footage from a Dollarama store captured the group—Brooks-Murray, Martell, Meadow, Lilly, and Jack—around 2:25 p.m. Brooks-Murray initially told police she put the older children to bed around 9 p.m. that night, later revising it to 10 p.m. She noted that Martell stayed up after she went to bed, and she was unsure when he joined her.

The morning of May 2 began quietly. Brooks-Murray marked the children absent from Salt Springs Elementary due to illness around 6:15 a.m. Between 8:00 a.m. and 9:40 a.m., the couple claimed they were in the bedroom with Meadow. Lilly reportedly entered the room several times, and Jack was heard in the kitchen. Then, silence. The adults discovered the sliding back door closed, but the children’s boots missing—Lilly’s pink ones and Jack’s blue dinosaur boots—along with Lilly’s white backpack featuring strawberries. No front door disturbance was noted; a wrench placed on it the previous night remained untouched. Martell said he immediately searched outside, driving back roads and checking culverts, while yelling their names.

At 10:01 a.m., Brooks-Murray called 911, reporting the children had likely wandered into the woods. Massive search efforts followed: Ground Search and Rescue teams, hundreds of volunteers, K-9 units, underwater recovery divers checking nearby ponds and Lansdowne Lake, and aerial support. By May 7, the search scaled back due to the unlikelihood of survival in the harsh terrain. No definitive evidence—such as clothing or footprints conclusively linked to the children—was found, though a child’s sock, boot prints in the woods, and a piece of pink blanket (possibly Lilly’s) were recovered and analyzed.

As weeks turned to months, court documents and media reports revealed troubling discrepancies. Two neighbors reported hearing a vehicle coming and going in the early morning hours—hours before the 10 a.m. 911 call—near the trailer. One witness described the sound as consistent with movement on the property’s driveway or access road. Yet, RCMP review of surveillance footage showed no vehicles during that window. In phone interviews, Martell denied any family departures or visitors that night, insisting no one left the property.

The vehicle in question ties into the family’s known transportation: a 2017 white Nissan Pathfinder belonging to Brooks-Murray. This SUV was used the previous day for the New Glasgow trip and features prominently in investigative records. Police obtained cellphone records for both adults under the Missing Persons Act, along with multiple search warrants. The nighttime vehicle sounds have fueled speculation that someone—possibly Martell—may have left the property during the hours when the family claims everyone was asleep, raising questions about the true sequence of events.

Martell has maintained his innocence throughout. He voluntarily underwent a polygraph on May 12, which authorities deemed truthful, as did Brooks-Murray’s. In interviews, he expressed frustration, anger, and shifting hope—from believing the children wandered off, to fearing abduction (urging border and airport monitoring), to later stating he no longer believed they remained in the nearby woods after exhaustive searches. By late 2025, on what would have been Jack’s fifth birthday (December 29), Martell reiterated doubt about their presence in the area.

The case has strained family ties. Brooks-Murray left the property shortly after the disappearance to stay with relatives elsewhere in Nova Scotia, reportedly blocking Martell on social media. The couple became estranged almost immediately. Online speculation has been intense, with true crime communities dissecting interviews, timelines, and statements. A $150,000 provincial reward for investigative leads remains active as of late 2025.

The white Nissan mystery, combined with the neighbors’ accounts of late-night vehicle activity, stands as a key element police continue to probe. Martell’s claim of sleeping through the night contrasts sharply with the reported sounds of a car—potentially the Pathfinder—arriving and departing. Why the discrepancy? Was there an unreported errand, or something more sinister? RCMP have interviewed dozens, including family members, and continue using major crime units, forensics, and technology.

Eight months on, with no bodies, no sightings, and no breakthroughs, the investigation remains open. Lilly and Jack’s paternal grandmother, Belynda Gray, has spoken publicly of fading hope, while the community clings to the possibility of answers. The case, described by RCMP as “extremely rare” in its officer’s 33-year career, underscores the agony of uncertainty in a rural setting where a simple wander could turn tragic—or where hidden truths may lurk behind closed doors.

The haunting question persists: If the children truly wandered off, why do the nighttime vehicle movements and conflicting narratives suggest Daniel Martell—or someone—may have gone somewhere that night?
