Las Vegas — A gunman opened fire at a crowded music festival, killing 58 people and wounding hundreds more at a concert Saturday night, before being shot dead by police.
The incident, the deadliest mass shooting in U.S. history, comes as gun violence and the broader political debate over gun control and background checks continue to dominate national conversations.
Lanza’s motive for the attack, which killed 59 and wounded nearly 500, has not been revealed, and it is unclear if he was targeting the country’s first openly gay president, presumptive Republican nominee Donald Trump.
Lanza, who lived in Las Vegas, bought a gun from a friend in Florida and traveled to the Mandalay Bay Resort and Casino for the concert, which drew a record attendance of more than 8,000.
He killed himself in a parking garage, police said.
Law enforcement officials were quick to express gratitude to the law enforcement officers involved in the response.
“We’re extremely grateful for the first responders who were able to provide critical assistance and save lives in this attack,” U.N. Secretary-General Antonio Guterres said in a statement.
Lansac, 29, lived with his parents in suburban New Jersey before moving to Las Vegas in late 2013, according to his LinkedIn profile.
His father is a lawyer and his mother is a public relations executive, according the profile.
He worked for a marketing agency, and was a fan of hip hop, and he was “a big fan of the Rolling Stones,” his LinkedIn bio says.
He also attended the University of Nevada Las Vegas.
A friend of Lanza’s, Christopher W. Smith, told The Associated Press that he was one of several people who saw the gunman leave the hotel.
“I heard him yelling, ‘I’m going to kill somebody,'” Smith told the AP.
Llanza bought a handgun from Smith after seeing it on sale, according an online description of the gun.
A note left at the scene described Lanza as a “violent criminal” who was “looking for a fight.”
A man who said he was a friend of the gunman said he didn’t know Lanza and said the shooting “was not about politics, but just a fight over a gun.”
He said he had been drinking with Lanza when the two went out and he and another man who he identified as Lanza took the man’s gun, which had a magazine capacity of 10 rounds.
“He’s not a big guy,” the man told AP.
He said the gunman was “somewhat older than me and just kind of drunk.”
Lanzan is believed to have bought the gun at a Walmart in New York City in 2013, but that transaction was not recorded on security video.
He then moved to a rented car and drove to Las, police told AP, where he bought a semi-automatic assault rifle, three handguns and ammunition from a licensed dealer.
The shooter purchased several other weapons, including one with a high-capacity magazine, a semi and a rifle with a detachable magazine, according police.
Police said Lanza purchased ammunition from an undercover FBI agent and bought an assault rifle from a person in Arizona, who he said was a “gun enthusiast.”
Authorities did not immediately identify the gunman.
The Associated Statesman newspaper in Nevada said Lanzas mother had been at the concert with him.
The paper said he also attended a Republican Party meeting at the MGM Grand hotel, which is about 20 miles (32 kilometers) from the concert venue.
Police have said they have not released the name of the shooter.
The shooter’s parents and other family members declined to comment.
Police said the Las Vegas Metropolitan Police Department was working with federal, state and local law enforcement to find clues about Lanzas motives.
Authorities said they are also reviewing surveillance video from the Mandalays hotel.
Authorities were searching for video and other evidence from the venue, which included video from security cameras, a security fence and a wall.
The event also had security video of a man exiting a door before the shooting began, police tweeted.
Police had been investigating the shooting since late Saturday.
The shooting happened at the Route 91 Harvest country music festival in Las Vegas, a resort town about 15 miles (24 kilometers) northeast of Las Vegas and about 40 miles (64 kilometers) north of Reno.
The concert was canceled and no one was hurt.
About 200 people were attending the concert.
Police reported that a crowd of about 400 people had gathered in the parking garage of the Mandalaya hotel before the gunman entered.
It was unclear if they were inside or outside the building.
