He found a police officer (Or a police officer found him? I am not sure.) and got reconnected with the group within five minutes. I understand the chaperones were panicked. His teacher didn't know until later. I am rather glad I didn't know until it was resolved. Scary. Hopefully he learned a lesson...in a safe and familiar environment. He doesn't seem at all upset by it, only embarrassed that he got lost...he was aiming for the restroom but clearly got very off course.
