It’s been almost a week since a gunman killed 58 people and injured hundreds more in Las Vegas. The shooter used a device called a bump stock to modify his gun so that it could function as a machine gun. Politicians have unified around one thing: further regulations around the bump stock. But dealers at a gun show in St. Charles this weekend said the demand for the bump stock was up.

Less than 48 hours after the massacre on the Las Vegas Strip that led to the deaths of 59 people including the shooter, details of the attack are coming into focus. And footage from police body cameras offers a new vantage point on the horrific events.

Police say they received the first call that shots had been fired at 10:08 p.m. Sunday night.

The suspect, 64-year-old Stephen Paddock, "fired off and on for somewhere between 9 and 11 minutes" in a dozen or so volleys, said Las Vegas Metro Police Undersheriff Kevin McMahill at a press conference Tuesday evening.

Less than 24 hours after the massacre at an open-air country music concert in Las Vegas, authorities are still piecing together what shooter Stephen Paddock did in preparation for his deadly shooting rampage that left 59 people dead and 527 others injured.

There is still a lot they don't know about what motivated Paddock, described by officials as a "lone wolf," to launch the most deadly mass shooting in modern U.S. history.
