NEWTOWN - A detailed report on the Newtown massacre is not due to be released until later this fall, but new information has been leaked about an incredible act of heroism that reportedly took place during the time of the shooting.

The mother of 6-year-old Jesse Lewis says she was not surprised to hear her son helped his fellow students, even securing their escape.

Scarlett Lewis says investigators told her that when the gunman, Adam Lanza, paused briefly to reload his weapon, her son Jesse yelled, "Run!", helping six students escape before he was shot.

Lanza killed 20 children and six women at Sandy Hook Elementary on Dec. 14 before committing suicide. He also fatally shot his mother.
