I see two different version of events from Gariepy one where she has a cell phone and one where she does not.
"He did so, in front of gas station cameras, he says. He says she remained in contact with him for the next two days before telling him she’d changed her plans, and that she would be discarding her phone."- Dailybeast
"Gariépy said Patoine, whom he calls Mama JF, left behind her credit cards and cell phone when she went on the trip." - News Week
"The police in Canada is looking for Mama JF because in true Mama JF fashion, she has left our home in June and has disappeared from the map. I am sure that Mama JF is fine, I know she has been safe for at least 2 days after I dropped her where she wanted in June," - News Week
