The investigation into the disappearance of siblings Lily Sullivan and Jack Sullivan has entered a new and closely watched phase, following confirmation that genetic testing is now underway on evidence recovered early in the case.

In January 2026, Daniel Martell, the children’s stepfather, voluntarily provided a blood sample to the Royal Canadian Mounted Police for DNA analysis. According to Martell’s statements to media, the sample will be tested against biological material found on a blanket that has remained in police custody since the early days of the investigation.

The blanket — a pink LOL doll-themed item belonging to Lily — has long been considered one of the most troubling pieces of physical evidence connected to the case.

A Blanket Found in Two Places

The blanket was discovered in May 2025, torn into two separate pieces and located in two different areas. At the time, authorities confirmed the discovery but offered little detail about its condition or significance.

Investigators have never publicly stated whether the blanket contained blood or other biological material. Martell has said he does not know exactly what substance is being tested, only that his DNA sample is being compared to something recovered from the fabric.

Police have declined to confirm or deny his account.

Voluntary DNA Submission

Martell has emphasized that his cooperation with investigators has been voluntary. He stated that he willingly provided the blood sample when requested and has not been informed of the specific nature of the testing.

The RCMP has refused to comment on whether the testing involves blood evidence, touch DNA, or another form of genetic material. They have also declined to say what investigators are hoping to determine from the analysis.

That silence has fueled speculation, but authorities have cautioned against drawing conclusions before results are known.

Why DNA Matters in This Case

Forensic experts note that DNA testing can play a decisive role in missing-person investigations, particularly when physical evidence has been recovered but lacked clear context.

If genetic material on the blanket can be identified, it may help establish who handled it, whether the blanket was exposed to violence, or if it traveled with one or both children after they disappeared.

However, investigators have not confirmed whether the DNA testing is expected to provide definitive answers or merely narrow the scope of the investigation.

RCMP Maintains Tight Control of Information

Throughout the case, the RCMP has maintained strict control over what information is released publicly. Officials have repeatedly stated that protecting the integrity of the investigation is their priority.

No arrests have been made in connection with Lily and Jack’s disappearance. Police have not named any suspects and have not confirmed whether the case is being treated as a criminal investigation or a missing-persons inquiry with criminal elements.

The decision to remain silent on the nature of the DNA testing suggests the evidence could be sensitive or potentially case-altering.

Public Attention Intensifies

News of the genetic analysis has renewed public attention and concern. The image of a child’s torn pink blanket has become a haunting symbol of the case, representing both innocence and unanswered questions.

Online discussion has intensified, with many observers questioning what investigators may have found on the blanket and why results are only being pursued now.

Authorities have not explained the timing of the testing or whether advances in forensic technology played a role.

What Happens Next

Once DNA analysis is completed, investigators will assess whether the results provide actionable leads. Even if a match is found, it may not immediately translate into public updates or legal action.

Experts caution that DNA evidence often raises as many questions as it answers, particularly when context is limited.

For now, the case remains open, unresolved, and deeply unsettling.

The RCMP has reiterated that the investigation is ongoing and that any information released will be done when it is appropriate and responsible to do so.

For the families involved — and for a public still searching for clarity — the DNA testing represents a fragile possibility: that long-standing questions surrounding Lily and Jack Sullivan may finally begin to move toward answers.
