The child who died was an 8-year-old BOY. He was waiting for his dad to cross the finish line, because his dad was in the Marathon. The boy died, his 6-year-old sister lost a leg, and his mother is in the hospital with a terrible head injury.
This is not true...this little girl is alive and well. It's all over facebook and is a hoax. I don't know why people do things like this...feeding on tragedy.
