Flavaine Carvalho, an Orlando, Florida waitress, helped a boy, 11, escape abuse. Carvalho noticed a boy with a family at a table didn’t receive food like the rest. Then, she saw bruises on his body. Thinking he might be in trouble, she secretly slipped a note to him: ’Do you need help? OK.’ The boy signaled yes and she called 911. A probe revealed the boy was systematically subjected to torture.
