Morris was pronounced on the scene, but Fields was taken to the hospital, where he did not survive.

The assistant fire chief says in addition to Philadelphia police, good Samaritan neighbors jumped in to help this family. He says a neighbor heard a child yell, rescued the mother of the child from the first floor and then went to the back of the house to try to rescue that child.

“He then went to the rear of the property, where he saw a young child, the second floor rear of that property. He urged the child to jump. The child did jump, the neighbor caught the child. They both fell, but the neighbor broke that child’s fall,” Assistant Fire Chief Harry Bannan said. “And that child sustained no injuries and that neighbor, through his actions, prevented some serious injuries to that child.”
