Police are auctioning off hundreds of guns, ammunition and other items from a crime spree that began in January and ended with a shooting at a luxury hotel in Vegas, according to police and other sources.
The spree was triggered by a botched robbery attempt at the Mandalay Bay Resort and Casino, which left three people dead and another two injured.
A manhunt was launched to find the gunman, identified as Stephen Paddock, but he escaped and fled into the desert.
The shooting that claimed the lives of 58 people was one of the deadliest in modern U.S. history.
“They have been out there collecting guns for a while now,” said one police source familiar with the investigation, who spoke on condition of anonymity.
“This was the biggest gun sale in history.”
The Las Vegas Metropolitan Police Department confirmed that at least 13 guns were auctioned off for $10 million or more.
The guns included .40-caliber Glock pistols, .357 magnums and .40 caliber shotguns, which are typically used for target shooting.
They also included handguns with silencers, and a rifle, which police say Paddock purchased legally but did not fire.
Police were able to track Paddock down in a nearby community after he bought a car and drove it to a casino, where he rented it.
He then went to a nearby casino, bought another car and bought a hotel room, where police say he bought guns and other gear.
Police are also searching for a vehicle believed to have been used in the attack.
As the investigation into the rampage continued, the police chief, James T. O’Neill, issued a statement saying that “we will continue to aggressively pursue those responsible for this tragic crime.”
Authorities say Paddock is believed to be armed with several guns and at least two rifles.
He was reportedly in possession of multiple weapons and ammunition, and he may have been planning another attack.
In addition to buying guns, Paddock also reportedly used stolen credit cards and money from family members.
Aurora, Colorado, resident Kevin T. Kratz said he had been at the MGM Grand Hotel and Casino when he heard a shooting.
Kratz, a retired police officer, said he and his wife were on the phone with their daughter, who is about 6 months old, when they heard a “pop.”
They quickly hid in the hotel room.
Within minutes, Kratsons mother called 911.
In the wake of the shooting, police were working to locate Paddock’s wife, Marilou Danley, a longtime casino employee and frequent gambler.
Police said they believe she left her home in nearby Redlands, California, after she and Paddock were both wounded.
Danley has not been identified.
