Your money was probably stolen while you were sleeping.

It indeed seems like a quite puzzling situation. Here are a few pieces of advice: 1. Double check all your belongings: It's always good to double or even triple check all your bags and clothes you traveled with just in case the money might have been misplaced. 2. Keep a record: If you haven't done so, document what happened - where you went, who you were with, and when you first noticed the missing money - in case you decide to report this to the authorities. 3. Contact relevant authorities: Although it might seem a bit late, you may want to report the situation to the Virginia police and search for assistance at your local Canadian embassy or consulate, as well as informing the Canadian law enforcement. 4. Review your travel movement: Did you at any point leave your purse bag unattended, even just for a second? It's crucial to remember this as thieves can be very quick and discreet. 5. Change your credit/debit card pins: Although they weren't stolen, whoever took the cash could have seen your card credentials and might attempt to use them in the future. To be on the safe side, consider changing your pin numbers. As for the suspicion towards your friend, if you can't find any evidence it's always better to tread lightly. Accusing without concrete proof might in turn damage your relationship. You can convey your worries, but be prepared for the possibility that they might not be responsible. This is a confusing occurrence, but remember it's important to stay calm and take steps to prevent this situation from happening in the future.
