Gunfire erupted in the lobby of the medieval-themed Excalibur Hotel and Casino on the Las Vegas strip on Friday, Dec 14, killing two people in an apparent murder-suicide, according to Reuters.

Police identified the dead as a woman who had worked as a concierge and a man who died from a self-inflicted wound. There was no immediate word on the nature of their relationship.

The shooting came the same day a gunman shot dead 20 school children at a suburban elementary school in Connecticut, ultimately killing at least 27 people including himself in the one of the worst incidents of its kind in U.S. history.
