The Nevada gun store that sold Stephen Paddock a gun on the same day he checked into the Mandalay Bay hotel has gone into lockdown in the aftermath of Sunday night's shooting.
News.com.au was refused access to Guns & Guitars in Paddock's home town of Mesquite on Wednesday a few hours after the store's manager, Chris Sullivan, had given an interview saying he felt no guilt about selling him the gun.
Mr Sullivan was not at the store at the time, having spent the day with lawyers.
Two staffers were guarding the doors outside the store, only giving access to local customers.
The men said "things got nasty" earlier that day when other reporters were questioning customers outside the store.
In an earlier interview with CBS News, Mr Sullivan revealed that he had sold Paddock a rifle on Thursday, September 28, and that he had sold him four other firearms over the past year.
Paddock checked into Mandalay Bay on September 28, where he stayed until he carried out his deadly massacre on Sunday.
The gun shop, which also sells musical instruments, is located only a five-minute drive from where Paddock lived in Mesquite.
Earlier Mr Sullivan said he felt "physically ill" to think that he had interacted with Paddock before he committed the Las Vegas shooting killing 59 people.
However when asked if he felt any guilt about selling him the firearms, he said: "I don't, no.
"We do everything right, we can't control what someone does once they leave this store."
The comments came following news Paddock had bought 33 guns between October 2016 and September 28, when he checked into the hotel.
"This morning over coffee I was having a moment in myself thinking 'I may have very well been the last person to shake hands with that man," Mr Sullivan said.
