A day after a massacre, Vegas is not quite Vegas

Few solitary gamblers sat with glassy eyes in front of slot machines

LAS VEGAS - The slot machines were still ringing and the drinks still flowing but the party didn't feel quite the same along the world-famous Las Vegas Strip on Monday evening, 24 hours after a gunman staged the bloodiest shooting in modern US history.

The somber mood was especially pronounced at the Mandalay Bay Resort and Casino, where police say a retiree with an arsenal of assault rifles rained hundreds of bullets into a crowd of concert-goers below his room, killing at least 59 and injuring more than 500.
