(CNN) — At least 50 people were killed in a mass shooting on the Las Vegas Strip, police said Monday. The shooting is deadliest in modern US history.

The suspect:

• Police have identified the shooter as Stephen Paddock, a 64-year-old man white male from Mesquite, Nevada.

• Police said in a statement that officers “breached the hotel room” where the shooter was located and “found the suspect dead.”

• The shooter had been at the Mandalay Bay hotel since September 28, 2017, the sheriff said. And “there was an excess of 10 rifles in the room.”

Investigation:
