BOSTON – A mother in Boston tells police her 8-year-old boy was shot to death in their apartment by gunmen in hooded sweatshirts during a home invasion.

Officers later receive a text message from an anonymous tipster that leads them to a much different conclusion: the boy's 7-year-old cousin accidentally shot him while the two boys were playing with a loaded 9 mm handgun.
