The investigation into Jack and Lilly Sullivan has just entered uncharted territory. Stepfather Daniel Martell has unexpectedly handed over a DNA sample to authorities—a move that has investigators and the public reeling. Coming from an interview recorded back in January, this ‘cooperation’ happened just before Martell was hit with separate charges. Is he trying to prove his innocence, or did he leave something behind that he knows the police will eventually find? The silence has been broken, and the lab results will be the final judge.

Authorities have not disclosed whether any forensic matches have been identified in connection with the children’s disappearance.

Martell’s interview with CBC occurred prior to the later charges. During that conversation, he discussed the emotional toll of the situation and the efforts to locate the children.

CBC has confirmed that Martell has not responded to its request for comment regarding the charges filed on Jan. 29.

Police have not announced arrests in connection with the disappearance of Jack and Lilly Sullivan. The investigation remains active.
