She observed Paddock constantly looking out the windows of the room, which overlooked the Las Vegas Village venue, the report said.
In May 2017, Paddock's internet search history included the terms "La Jolla Beach", "biggest open air concert venues in US", and "how crowded does Santa Monica Beach get", according to documents made available by the Las Vegas Metropolitan Police Department.
"You are all going to have to be patient and let the investigation run its course", Lombardo said.
The 64-year-old retired accountant and real estate investor had lost a "significant amount of wealth" since September 2015, which led to "bouts of depression", Sheriff Lombardo said.
Police also found notepads strewn around the room which had technical notes and reminders such as "unplug phones" and measurements including distance and bullet drop calculations.
Other determinations from the report included the revelation of hundreds of images of child pornography on Paddock's computer and the fact that one other unnamed person is under investigation. He had paid off all his gambling debts before the shooting.
He had previously told friends and relatives that he always felt ill, in pain and tired.
The killer's estranged brother, Bruce Paddock, was arrested in October on child-pornography charges.

Afflalo reportedly apologized to his teammates before practice and addressed the media about the incident. The big scuffle was just the breaking point. "I just want to say I think I did the right thing".
Google search history in an HP laptop showed Paddock researched other large-scale venues, including locations in Boston, Los Angeles and San Diego, the report said.
After Paddock checked into The Ogden in downtown Las Vegas on September 17, searches for Las Vegas locales were registered, including "Excalibur Hotel & Casino", "Fremont Hotel & Casino", "NV gun shows", and "How tall is Mandalay Bay".
Investigators found 23 guns in the rooms, including 12 rifles fitted with "bump stock" devices that allowed rapid-fire shooting similar to fully automatic weapons. Police also found a blue plastic hose with a fan on one end and a snorkel mouthpiece on the other end inside the room.
The sheriff also did not say what charges the federal grand jury is considering.
However, he said the FBI was investigating another person of interest, but would not identify them.
"Let's face it, ISIS, twice before the attack, warned the USA they would attack Las Vegas... and then after the attack claimed responsibility four times".
Danley was in the Philippines at the time of the shooting.
Danley also said Paddock had been behaving oddly for the previous year of his life and she thought he was breaking up with her when he unexpectedly wired her $100,000 prior to the shooting.
