God bless the brother.
There is a program on the Christian broadcasting station(TV) that has a guest every year that discusses how many young people are TAKEN and FORCED into the SEX trade.
Often foreign, not always. They are made to be drug addicts, and are closely monitored and locked up, etc.
It is big business. The youths travel the United States and are mostly on the go continually.
It is not too late to check all these sources out.
COLD Cases do get solved.
