LAS VEGAS - Retiree Stephen Paddock had a well thought-out plan to wreak massive carnage at a country music festival on Sunday (Oct 1) while holding the police at bay.

Details that emerged about the 64-year-old former accountant in the aftermath of the attack that killed 58 people and injured more than 500 others showed a well thought-out plan.

Here's a quick look at how the shooting unfolded:

Thursday (Sept 28 )

Paddock checked into a two-room suite on the 32nd floor of the Mandalay Bay Resort and Casino. He had at least 10 suitcases in the suite, which might have been used to bring the rifles and ammunition in without notice. A search of the suite after the attack found 23 rifles, hundreds of rounds of ammunition and other equipment.

Paddock kept the "Do Not Disturb" sign on his door for the next three days and so no maids entered the suite, according to a hotel worker.

In the period leading up to the shooting, Paddock created a ring of surveillance around him, with video cameras in his suite and in the hallway, law enforcement officials said. The cameras were apparently intended to warn of approaching threats.

Country music singer Jason Aldean began his performance at the Route 91 Harvest, an annual Las Vegas music festival. There were more than 22,000 people in the crowd.

10.05pm

Paddock opened fire on the concertgoers from the windows of his hotel suite, firing long, rapid-fire bursts as people ran for their lives, trampling over one another. He was believed to have fired from both rooms to get different angles.

10.12pm

Two officers arrived on the 31st floor of the hotel and said the gunfire was coming from above them.

The last shots were heard. 

10.17pm 

The two officers arrived on the 32nd floor.

A security guard was shot as more than 200 rounds were fired from the suite into the hallway.

10.26pm-10.30pm

Eight more police officers reached the 32nd floor and began clearing each room and searching for wounded.

11.20pm

Officers used explosives to breach the door of Paddock’s room. They found him on the ground.
