This development is unbelievably heartbreaking!
Another victim has been identified in yesterday's horrific attack on Boston: 29-year-old Krystle Campbell of Medford, Mass..
Sadly, she wasn't even a runner in the marathon. Krystle was waiting for her friend's boyfriend to finish the race when bombs went off near the end of the course and killed her.
Her father, William A. Campbell Jr., spoke about the shock and grief he is experiencing.
