Two Nevada gun shops confirmed to NBC News Monday that they sold firearms to Mandalay Bay shooter Stephen Paddock in the last year and said he passed all required background checks.
It was unknown if the weapons Paddock bought from the gun shops, New Frontier Armory in North Las Vegas and from Guns and Guitars in Mesquite, were used in the casino massacre.
Christopher M Sullivan, the general manager of Guns & Guitars, Inc., in Mesquite, Nevada, released a statement confirming Paddock was a customer at his store. Sullivan said "all necessary background checks and procedures were followed, as required by local, state, and federal law."
"He never gave any indication or reason to believe he was unstable or unfit at any time," he said. "We are currently cooperating with the ongoing investigation by local and federal law enforcement in any way we can."
