So to summarize the theories: we've got one boyfriend who is conspiring with a person or persons unknown in the Cities to make sure his phone is answered while he's in Grand Forks (300+ miles one way) kidnapping her but back in the Cities to talk to the cops, and, back in Grand Forks, she's getting harassing phone calls from someone with a foreign accent, there's someone else who wants more from the relationship than she's willing to give, and Grand Forks seemingly studded with ex-boyfriends of hers--none of whom could have possibly done it.

Have I missed anything?

The boyfriend's story doesn't quite reach plausibility, especially when you try to explain the delay in calling the cops. If this were to actually happen to my wife, and she were on the phone with me at the time, I would be on 911 instantly.
