Reports have emerged which claim that Las Vegas gunman Stephen Paddock may have been planning more attacks, possibly including a car bombing.
It is understood that Paddock may have booked a hotel room in Chicago, which overlooked a music festival at the time.
According to a Nine News report, Paddock backed out at the last minute.
Police have shared information suggesting that Paddock may have also believed that he was going to escape after the attacks, with his car found in the parking lot below the Mandalay Bay Hotel.
The car is reported to have contained a large quantity of explosives and ammunition - leading authorities to believe that a second attack may have been on the cards, including a car bombing later that night.
The possibility that an accomplice was involved is still being examined by police, as there remains the question of how Paddock was able to stockpile and set-up this many weapons.
