ATLANTA -- In the affluent Atlanta suburbs, there's a deadly secret.

Young people are dying from heroin. There are some people who don't want you to know about it.

The GBI confirms the fastest growing rate of heroin-related deaths is in a cluster of Atlanta's northern wealthy suburbs. That fact is hiding in state and county records. Inside the Triangle is the story of how we found the truth.
