What was it, 9 minutes after they found her, they found him? I'm assuming that the dog walker called 911. How far away from him was she when she found the lady who saved her?
If he thought he had her "broken" - or he thought she was secured, he could have been out shopping or at work, even. If Jayme knew where he was, then easy enough to just go pick him up.
That said, I really hope she whacked him over the head with a two by four and knocked him out before she made her escape.
