A picture finally led to a reunion, more than a year after Philadelphia's deadly Amtrak crash.
The photo shows first responders carrying and ultimately saving a severely injured passenger named Robert Hewett.
Fast forward to last week, and Hewett finally got to meet some of the men he calls his guardian angels.
They got together for lunch after one of their wives recognized Hewett's story and reached out to him.
Hewett says he will be forever grateful for their bravery.
