Almost a week after a mother and her two children mysteriously vanished from their Chateauguay, Que. home, police are asking the public for help in a case that, so far, has few leads.

Erin Gray and her children, 11-year-old Rachel Kaya Beckles and 5-year-old Robert Clark Jr., were last seen in Kanawake on Sunday, June 22. That's when Gray's sister Ashley said the 33-year-old mother and her children picked up laundry at her house there, and then hurried away.

"My daughter, a few hours later, told me Auntie Erin came and got her laundry," Ashley said. "Later, I found out that when she got outside with her laundry she was running to her car, like in a rush."

Gray's mother Jackie said she doesn't believe Gray ever returned home after that.

"She was gone, just gone. We don't know how," Jackie said.

Gray also saw her Jackie earlier on Sunday. Jackie said Gray seemed ordinary during the visit.

"There was nothing weird or strange about her. It was a normal day," Jackie said of seeing her daughter Ashley before the disappearance.

But everything hadn't been completely normal in the months leading up to last Sunday. Jackie said that Gray talked about being followed.

"She kept saying that somebody was following her, she was being stalked," Jackie said. "I didn't even take her seriously."

Jackie said Gray never gave specifics about the people she believed were following her, but she did say that it was "a bunch of people," not a single stalker.

"I kept saying, 'Erin, I don't know. Is it in your mind?' " Jackie said. "I really didn't take it seriously. Maybe I should have."

Gray's family says she has no history of substance abuse, or mental illness.

When Jackie went to Gray's house on Monday, she discovered it in disarray.

There were clothes missing from the closet and food left sitting on the counter. Gray's car, a 2001 Buick Century, was also missing.

"It looks like she left her home in a rush," Jackie said.

There was false hope on Thursday, June 26, when police received a tip that Gray and her children had been spotted in Gatineau. But it turned out to be another woman who looked so similar that even Jackie and Ashley thought that Gray had been found.

"The biggest hope was Gatineau," Jackie said. "It was an identical family."

Now, Jackie, Ashley, and the police are turning to the public to ask for help in finding Gray and her children. Anyone with information is asked to contact the Chateauguay police at 450-698-1331 ext. 7.
