The 32nd-floor hotel room was transformed into a sniper’s nest by the 64-year-old as he indiscriminately fired towards the crowd of 22,000 people enjoying the Route 91 Harvest country festival on the Las Vegas Strip.
Authorities found 23 guns after storming the room and finding the killer dead, in what is believed to have been a suicide attempt, after he had taken the lives of 59 people and injured more than 500 others.
A glimpse through the shattered windows of his hotel suite reveals a series of lamps still lit alongside various pieces of luxury furniture.
The depraved murderer is believed to have only been found after his smoke alarm went off, alerting police to his location.
Paddock had been feeding guns with thousands of rounds of ammunition and while the details of the firearms he used have not been disclosed, questions are being raised about whether or not the former accountant had managed to get his hands on an automatic weapon, also known as a machine gun, to inflict as much damage as possible.
He is believed to have moved into the suite, which looks down onto the Las Vegas Village festival ground, on September 28 – giving him several days to gradually move the weapons and ammunition to his room using suitcases.
He smashed through two of the hotel suite windows to create sniper perches before firing on the innocent civilians.
Some of the weapons discovered in Paddock’s hotel room had scopes, making it easier for him to target the concertgoers from long range.
Long bursts of gunfire came as 64-year-old Stephen Paddock fired indiscriminately towards the 22,000-strong crowd, sending thousands fleeing into the streets in fear as the chaos unfolded in what has become the deadliest mass shooting in US history.
Speaking about the Mandalay Bay room, Las Vegas undersheriff Kevin McMahill told CNN: “This is a day I wish I never had to see in my 27 years of law enforcement,” adding that he had never witnessed anything like it in his career.
As investigations into the gunman continue it has emerged that the 64-year-old was a millionaire who lived in a quiet retirement community in the Nevada desert.
The wealthy former accountant had had a pilot’s and hunting licence and no criminal record, according to police.
One former neighbour described the keen gambler as “weird” as according to some sources, there is reason to believe the suspect had a history of psychological problems.
Despite a claim from Islamic State, Paddock is not believed to have had any connection to any militant groups, leaving more questions surrounding his motive for committing the terrible atrocity.
The killer’s brother, Eric Paddock, told reporters their father was a bank robber who used to be on the FBI’s most wanted list and once escaped from prison.
He said his family were “stunned” by the news, adding: “There’s absolutely no sense, no reason he did this.
“He’s just a guy who played video poker and took cruises and ate burritos at Taco Bell.”
