Chateauguay police said they received a report that a woman who'd been missing from the south shore community since last Sunday may have been spotted Thursday evening in Gatineau.
Pictures were made public that appeared to suggest that the woman and two young children were the missing trio.
Police said late Friday that the pictures were not of the missing mother and two children.
33-year-old Erin Gray vanished on Sunday, June 22, along with her 11-year-old daughter Rachel and 5-year-old son Robert. She was apparently seen at a Walmart in Gatineau.
Her sister Melissa told CJAD's Barry Morgan earlier Friday that news of her sighting came as a relief, but also raised more questions.
Other family members say Erin had been showing signs of paranoia in the months leading up to her disappearance — insisting that various people were following her and her children.
But according to her mother Jackie, she had been improving in recent weeks.
Police say Gray was driving a beige 2001 Buick Century with a noisy muffler. The licence plate number is X08 EDT.
