The heartbreaking mystery surrounding the disappearance of two young Nova Scotia siblings—six-year-old Lilly Sullivan and her four-year-old brother Jack—has taken yet another dramatic twist, as police conducted a second round of polygraph tests amid growing questions about a so-called ‘family secret’ that the children’s devastated mother has now reportedly confirmed in an emotional revelation.

Malehya Brooks-Murray, the mother of the missing pair, spoke out in a tearful interview, admitting there are painful family truths that have weighed heavily on her throughout the agonizing 11-month ordeal since her children vanished from their rural home in Lansdowne Station, Pictou County, on May 2, 2025. While she has consistently passed multiple lie-detector examinations—including the latest round—her candid acknowledgment of hidden family issues has sent shockwaves through the tight-knit community and reignited speculation about what really happened on that fateful spring day.

‘I can’t keep pretending everything was perfect,’ Brooks-Murray told reporters in a voice trembling with grief. ‘There are things in our family—secrets, struggles—that no one should have to carry alone. But I swear on my life, I did not harm my babies. The polygraphs prove it, and my heart breaks every second they’re not home.’ Her words, raw and unfiltered, have fueled intense public interest in a case that has gripped Canada and drawn international attention, with search efforts, massive tip lines, and forensic scrutiny yielding heartbreakingly few answers.

The latest developments come courtesy of the Nova Scotia RCMP, who confirmed that an additional round of polygraph examinations—commonly known as lie-detector tests—took place in February 2026. While authorities have remained tight-lipped about exactly who was tested or the specific questions asked, sources close to the investigation reveal that at least some of the focus shifted to one of the few tangible pieces of evidence recovered: a light pink blanket discovered hanging mysteriously in a tree near the family’s property.

That blanket, believed to belong to Lilly, became a haunting symbol in the case. Found days after the initial disappearance during one of the exhaustive grid searches of the dense woods surrounding the home, it has been subjected to forensic analysis at the RCMP’s National Forensic Laboratory. Two of the recent polygraphs were reportedly centered on questions about the blanket—how it ended up in the tree, who might have placed it there, and whether it holds clues to the children’s fate.

Brooks-Murray herself confirmed to media outlets that she underwent a second polygraph and was informed she passed once again. ‘They asked me everything—about the blanket, about that day, about our home life. I answered truthfully every time,’ she said. Her stepfather, Daniel Martell, who has been living with her and the children, did not comment on whether he participated in the latest tests, though earlier court documents showed he too passed initial polygraphs in May 2025.

The children’s disappearance was first reported when Brooks-Murray frantically dialed 911 just before 10 a.m. on May 2, claiming the siblings had wandered away from the backyard while she was briefly inside. What followed was one of the largest search operations in Nova Scotia history: hundreds of volunteers, ground teams, helicopters, cadaver dogs, divers scouring nearby waterways, and even assistance from RCMP units across provinces.

Despite combing thousands of acres of thick forest, reviewing over 8,000 video files, conducting 75 interviews, and following up on more than 1,000 tips, no trace of Lilly or Jack has ever been found—no clothing, no footprints, no signs of struggle. The pink blanket remains the only physical item definitively linked to them post-disappearance.

Court documents unsealed over the months have painted a complex picture of the family’s dynamics leading up to that day. Brooks-Murray and Martell had been in a common-law relationship for about three years, living together with Lilly, Jack, and a younger child. Files revealed allegations of past physical abuse by Martell toward Brooks-Murray, though she has since emphasized that those issues were being addressed and had no bearing on the children’s vanishing.

Polygraphs have played a central role from the start. Initial tests on May 12, 2025, at the Bible Hill detachment saw both Brooks-Murray and Martell pass questions about whether they caused harm to the children or knew their whereabouts. Subsequent tests—including ones with other family members like Martell’s mother and the children’s biological father, Cody Sullivan—also indicated truthful responses in most cases.

Yet the second round has intensified scrutiny, with some questioning why more tests were needed nearly a year later. RCMP insist all scenarios remain open—abduction, accident, or something more sinister—though they have repeatedly stated there is no evidence of foul play involving the immediate family.

The mother’s recent confirmation of a ‘family secret’ has only added fuel to the fire. While she has not elaborated on specifics—citing privacy and the ongoing investigation—online forums and social media have buzzed with theories ranging from domestic turmoil to hidden custody battles or even undiagnosed mental health struggles within the household. Brooks-Murray has begged the public to focus on finding her children rather than speculating.

‘People don’t understand the pain of waking up every day without them,’ she said. ‘The secrets are about our past pains, not about hurting Lilly and Jack. I would give anything to hold them again.’

The community of Lansdowne Station—a quiet, sparsely populated rural area about 140 km northeast of Halifax—remains deeply scarred. Neighbors describe the family as ordinary, with the children often seen playing outside. Vigils continue, yellow ribbons tied to trees, and a dedicated Facebook group with thousands of members shares updates and pleas for information.

RCMP have described the case as ‘extremely rare’ and ‘complex,’ vowing to leave no stone unturned. Investigators have emphasized that polygraphs, while helpful in eliminating suspects, are just one tool in a multifaceted probe that includes advanced forensics, behavioral analysis, and tip follow-ups.

For Brooks-Murray, each new development reopens old wounds. She has spoken of the toll on her remaining child, the younger sibling left behind, and the constant ache of uncertainty. ‘They were my everything—curious, loving, full of life. Lilly with her big dreams, Jack with his giggles. I miss them every breath.’

As the investigation grinds on into its second year, the pink blanket dangling in that tree continues to haunt searchers and the public alike—a silent clue in a puzzle with too many missing pieces. With the latest polygraphs complete and the mother laying bare a family secret, the desperate hope remains that truth—and the children—will one day emerge from the shadows of those Nova Scotia woods.

The nation watches, prays, and waits for answers in a disappearance that has shattered hearts and defied explanation. Lilly and Jack Sullivan are still out there somewhere—or so their loved ones cling to believe—and until they are found, the questions, the tests, and the grief will persist.
