DENVER (AP) — The parents of a 16-year-old boy who wounded two students at a Colorado high school with an old revolver his family said was kept in a locked gun safe won’t be charged with any crimes, authorities said Wednesday. Investigators looked at whether the parents of Desmond Holly, who killed himself after opening fire, could possibly be charged with allowing access to the Smith & Wesson .38 special revolver or for not storing it safely, but decided there wasn’t enough evidence for that,
