A list of the deadliest mass shootings in modern US history

An outdoor concert in Las Vegas has become the deadliest mass shooting in modern US history with at least 58 dead and another 515 injured. Police identified Stephen Paddock, 64, as the gunman who rained gunfire from a 32nd-floor window at the Mandalay Bay hotel on the Vegas strip.

Paddock was armed with 10 rifles and had been a guest at the hotel since Thursday. Authorities found several more weapons when searching Paddock’s home in a retirement community in Mesquite (about 90 miles northeast of Las Vegas).

According to police, Paddock has no criminal record and the motive for his attack is unknown.

The death toll in Las Vegas has eclipsed last year’s massacre of 49 people at an Orlando nightclub by a gunman who pledged allegiance to the Islamic State.
