What we know, don’t know about Las Vegas shooter

WHAT WE KNOW:

• A gunman whom authorities have identified as Stephen Craig Paddock opened fire on concertgoers with an automatic weapon from the 32nd floor of the Mandalay Bay casino-hotel tower on the Las Vegas Strip, killing at least 59 people.
• SWAT teams using explosives stormed the gunman’s hotel room and found he had killed himself, authorities said. Asst. Clark County Sheriff Todd Fasulo said officers found 23 firearms in Paddock’s hotel room and 19 firearms at his home in Mesquite, Nevada.
• Paddock, 64, who lived in a retirement community in Mesquite, Nevada, was not known to local or federal authorities.
• Authorities in Texas say he lived in a Dallas suburb from 2009 to 2012. He owned at least three rental properties.
• Paddock had no known connection to an international terrorist group, the FBI said. Earlier, the Islamic State group claimed Paddock was a “soldier” who had converted to Islam recently, but did not provide any evidence.
• He was a multimillionaire who made much of his money investing in real estate, his brother Eric Paddock, said.
• Eric Paddock said his brother also worked as an accountant and “played high stakes video poker.”
• Public records show that Paddock has both a pilot’s and hunting license.
• Eric Paddock also told reporters that their father was a convicted bank robber who was added to the FBI’s Most Wanted list after escaping prison in the 1960s.
• Mesquite Police Chief Troy Tanner says police surrounded and entered the single-family home where Paddock lived with Marilou Danley early Monday morning. The one-story, three-bedroom home is in the Sun City Mesquite retirement community, about 80 miles north of Las Vegas.
• Las Vegas police were looking for Danley, 62. They found her out of the country and have since determined she is no longer considered a “person of interest” in the shooting, police said. Eric Paddock called her his brother’s girlfriend.
• Paddock had first checked into the hotel on Sept. 28.
• He apparently used a hammer-like device to smash out windows in his room and opened fire, authorities said. Some 527 people were injured, Las Vegas Metropolitan Police said.
• The assault, at the Route 91 Harvest country music festival, is the deadliest mass shooting in modern U.S. history.
• As many as 22,000 people were at the concert. The shooting sparked panic; thousands fled, in some cases trampling one another as law enforcement officers scrambled to locate the gunman.
• White House spokeswoman Sarah Huckabee Sanders said President Donald Trump was “briefed on the horrific tragedy in Las Vegas.” Trump tweeted his condolences to all affected by the shooting. The U.S. Homeland Security Department says there is no “specific credible threat” involving other public venues in the United States.
• Country music star Jason Aldean was in the middle of a song when the shooting started. He later posted on Instagram that he and his crew were safe. He called the shooting “beyond horrific.”
• Pope Francis called the Las Vegas shooting a “senseless tragedy” and assured victims they are in his prayers.
