It's unthinkable: The horror of losing a child in a tragic fire. But now imagine police think you did it.
Kristine Bunch lived that nightmare, and now after being locked away for years over the death of her son, she's on a road to redemption.
Bunch spent more than 15 years behind bars, convicted of killing her 3-year-old in a fire. She has always maintained she didn't do it . And now the evidence seems to be backing her up.
Not only does the evidence point to her being not guilty -- some of it even appears to be doctored to make her look like a killer.
