At least 50 people were killed late Sunday night in a mass shooting during a concert on the Las Vegas Strip. Here's what we know about Stephen Paddock, the man police identified as the shooter:
Paddock, 64, is from Mesquite, Nevada, authorities said. Police stormed his hotel room from which they believe he fired the shots on the 32nd floor of the Mandalay Bay Resort and Casino. They say he had over 10 rifles when police found his body. The believe he killed himself prior to entry. He checked into the hotel on September 28th.
Paddock was apparently targeting a crowd of 30,000 people attending the Route 91 Harvest music festival below. Police believe he killed himself prior to entry into the hotel room.
Police are also at his home in Mesquite, Nevada. They are methodically investigating the property. The Mesquite Police Department had no prior contact with him, according to spokesman Quinn Averett, nor had there been any calls to Paddock's home in Mesquite, which is about 80 miles northeast of Las Vegas. Officials did not know how long he had been living in the area.
This mass-shooting is not yet considered an act of terrorism. Police are looking into a motive for the shooting before they can call it an act of terror.
So far, the massacre has no known link to overseas terrorism or terror groups, a US official with knowledge of the case said.
And a woman described as a "person of interest" after the attack is not believed to be involved in the shooting, police said in a statement.
"Marilou Danley is no longer being sought out as a person of interest," the Las Vegas Metropolitan Police Department said. "LVMPD detectives have made contact with her and do not believe she is involved with the shooting on the strip."
• Police have identified the shooter as Stephen Paddock, a 64-year-old man. He was earlier described as a "local resident."
• Officers said they engaged the suspect at the Mandalay Bay hotel, and he was killed.
• Police do not believe there are additional shooters.
• Police report there are now at least 50 dead and some 200 injured, making this the deadliest shooting in modern US history. The 2016 Pulse nightclub shooting in Orlando, Florida, was previously the deadliest, with 49 killed.
• Two off-duty Las Vegas police officers were killed in the shooting, Sheriff Joseph Lombardo said at a news conference.
• Two other officers responding to the scene were wounded, the sheriff said. One of them is in critical condition.
• Police said they are confident they have located Marilou Danley, who was traveling with the suspect. She had been sought for questioning in connection with the shooting. She is not named as a suspect.
