FIRST Global told Fortune that all students are provided safe transportation to their dormitories after the daily competition and are always “to be under close supervision of their adult mentor and are advised not to leave the premises unaccompanied by the mentor.”
The Metropolitan Police Department tweeted photos and information of the missing teenagers Wednesday. More information and their descriptions can be found on the police department’s website. Anyone with information is asked to call the Youth & Family Services Division, who is investigating the case.
