Have you a concrete case of a child recognized thanks to a high profile campaign ?
Several:
- Jaycee Duggard and Elizabeth Smith were found because they had never been forgotten by police officers.
I'll post the articles if I find them (some seem to have been taken offline, possibly to protect the victims)
- Shannon Mathews: someone reported a suspicion.
- Simon Jones: missing for 56 days - someone found that a little boy living with a man in a hostel did not seem normal and reported suspicious activity to the police.
- One of the Chinese abductions (which I posted a few days ago) resulted in a member of the public contacting the family. There may be many more of these, but I don't understand Chinese.
- Stephanie (Germany or Austria): someone found a little note that she had managed to drop near a recycling bin. Instead of letting the note rot in the rain, someone picked it up out of precaution and took it to the police.
- A young French adolescent who had disappeared from a camping ground.
That's just off the top of my head.
