I'm really hopefully freaking out about nothing, but I am working with a Canadian student based at a high-ranking US university, and I haven't heard from them at all after they were supposed to get back to their university after an international trip.

Are they being a typical busy grad student and just not responding to email or texts? Or are they sitting in a cell in a for-profit concentration camp somewhere? I can't believe this is a thing I have to consider. FUCK.
