Las Vegas shooting: Photo of gunman Stephen Paddock released

Reporting on the deadly mass shooting in Las Vegas, NBC justice correspondent Pete Williams tells TODAY that police are on the scene at the home of gunman Stephen Paddock in Mesquite, Nevada, some 82 miles away from Las Vegas, where they are checking for booby traps. The first photo of Paddock has been released by police, and video shows the shattered 32nd-floor hotel window from which he opened fire on a concert crowd of 22,000, killing at least 50 people and injuring hundreds more.
