Police have polygraphed family members of the two toddler siblings who disappeared from their rural home in eastern Canada on May 1.

Jack Sullivan, 4, and his sister Lily, 6, were reported missing by their mother, Malehya Brooks-Murray, a day later. 

Over the four months they have been gone, the local police have received more than 760 tips from the public, none of which have gotten them any closer to finding the children.

Highlights

  • Jack Sullivan, 4, and Lilly Sullivan, 6, vanished from their Nova Scotia home on May 1.
  • Police have since polygraphed their mother, stepfather, grandmother, and biological father.
  • The grandmother’s polygraph results were inconclusive.

Police have since polygraphed the mother, the stepfather, Daniel Martell, the children’s grandmother, Janie MacKenzie, and their biological father, Cody Sullivan.

The revelation was made in Royal Canadian Mounted Police(RCMP) documents, which indicated that the children were first reported missing to Nova Scotia law enforcement at 10:01 a.m. on May 2.

It is unclear when the mother became alarmed, but she initially thought the children had wandered away from their house, which is near a heavily wooded area. 

Police arrived 26 minutes after Malehya’s call and discovered a pink piece of Lilly’s blanket less than a mile from their home. They deployed a sniffer dog, but with no results.

They would later find another piece of the same blanket in a trash can closer to their home.

The grandmother’s polygraph test proved inconclusive

Although polygraph test results are inadmissible in Canadian courts, the RCMP uses them as a tool in their investigations.

Following tests on the mother and stepfather on May 12, documents seen by the local CTV outlet proclaimed that both had been honest and forthcoming in their initial accounts of Jack and Lilly’s disappearance.

Investigators then subjected grandmother Janie MacKenzie to the same treatment but determined that her results were inconclusive.

The estranged biological father was home on the day his children went missing

Attention was also drawn to the children’s biological father, Cody Sullivan, after Malehya told police he might have collected them and taken them to New Brunswick, where he lived, which is over two hours away by ferry.

Another report backed this idea up when a suggestion bearing the same sentiment was phoned in to the police.

But after confronting the father on May 22, police learned that he was home on the day of his offspring’s disappearance, and while he paid maintenance for the children, he had not been in contact with them or the Malehya for three year

ADVERTISEMENT“He was home on May 2, 2025, and never goes anywhere. He has not been anywhere other than his house recently and has had no contact with Malehya since the children went missing,” the document reported.

One tipster claims they saw a boy and a girl walking toward a woman who was waiting for them by a car

One of the 760 tips received by the RCMP claimedthat a duo matching Jack and Lily’s description was seen walking hand-in-hand towards a woman nearby their home.

Said woman, described as being between the ages of 50 and 60, was waiting beside the open back door of a sedan.

The witness who submitted the tip, however, estimated that the children were between the ages of 9 and 10.

While police are still probing the claim, the report asserts that “none of the tips so far have led to Jack and Lilly’s location or has any information that has been corroborated by the investigation.”
