The slaying of four college students is taking more twists and turns. Cops have reversed an earlier advisory that citizens needn't be worried for their safety...they also say two other roommates were home during the slayings, and they're searching local hunting shops for a particular kind of knife.

Plus, It’s been more than a half a century since a White House family wedding was held at 1600 Pennsylvania Avenue. This weekend the granddaughter of President Biden will say her “I do's” on the South Lawn. And the holiday travel season is upon us and some female fliers have had it with certain guys invading their personal space. Ann Mercogliano explains.
