Room service receipts from the Las Vegas shooter's stay at the Mandalay Bay resort and casino reveal his insatiable appetite - and raise questions about the official timeline of the massacre.

A man who works at the Mandalay Bay posted a receipt to Facebook Tuesday night, claiming that he served Paddock in his suite on the 32nd floor of the hotel.

The receipt shows that on September 27, Paddock ordered a large meal to his room including a burger, a bagel, potato soup, a bottle of water and two Pepsis.

Four days later, Paddock used the same room to open fire on a music festival taking place across the street - killing 58 and injuring 527.

The receipt says that the meal was for two people, but it's unclear if there actually was another person in the room.

Police previously said that Paddock used his girlfriend's ID when he checked in, so that could account for the count of people staying in the room.

The receipt also disputes the official timeline of the massacre. Police have said that Paddock checked into the hotel on September 28, but the receipt seems to prove that he was there at least one day earlier.

And another source told journalist Laura Loomer that Paddock was actually checked in as early as September 25.

The person who posted the receipts has since deleted the pictures, but his profile still says he works at the casino. Loomer took a screenshot of the receipts before they were deleted.

Meanwhile, Mesquite, Nevada neighbors are speaking out to detail more about Paddock's private life before he carried out the deadliest shooting in U.S. history.

Some say they never set eyes on the man accused of spraying an outdoor concert with bursts of gunfire from high above in a Las Vegas hotel window on Sunday, killing 58 and wounding more than 500, before shooting himself.

Tracing Paddock's footsteps in Mesquite, the Nevada desert retirement community about 90 miles northeast of Las Vegas, provides scant clues about why, according to authorities, he carried out the worst mass shooting in recent U.S. history. Hardly anyone noticed the man.

'Nobody knew him. I literally never saw him,' said a neighbor who lives two doors down from Paddock's home and who declined to be named.

'The house was so quiet, we thought they were snowbirds,' he added, referring to retirees who spent the winter months in warm-weather places like Mesquite.

Garbage cans were put out on the street before anyone else was even awake, leaving no opportunity for casual chats with neighbors living just feet away.

Yard work was done by gardeners. Pizza came directly to the door, and as far as anyone knew, Paddock never took part in bingo or bocce, or any of the social activities provided by the retirement community.

By all accounts, Paddock was a man of few words who never sought to interact with others beyond his live-in companion, Marilou Danley, a 62-year-old former casino employee described by authorities as person of interest in the investigation.

Neighbors immediately next to Paddock's mustard-colored stucco home, landscaped with stones and desert plants, displayed a sign on their door: 'We did not know him.'

The mangled remains of Paddock's garage door sat in his driveway, after authorities searched the home on Monday, uncovering a cache of 19 firearms, explosives and thousands of rounds of ammunition.

Paddock, who worked as an apartment manager and aerospace industry worker over the years, was known as an avid gambler. He would venture out of his Mesquite home frequently to play poker at the local casinos, where regulars recalled his face but little more.

The 64-year-old would often stop at Starbucks, where baristas remembered him as quiet and 'in his own world.'

And according to one barista, Paddock appeared 'rude' when he ordered a Mocha Frappucino for Danley, instead of letting her order for herself.

'He didn't let her talk,' the employee said.

Paddock seemed more sociable to those who delivered him pizza from Domino's 14 times in recent months.

A good tipper, Paddock paid cash and always ordered the same thing - two medium mushroom pizzas with extra cheese.

The receipt seems to contradict police reports that Paddock checked into the Mandalay Bay (pictured on Monday) on September 28. Another source said he checked in on September 25

Sometimes he would tell the delivery person he was trying to lose weight and the pizza was only for his companion.

Domino's employee Jessie Givens recalled that Paddock would joke to her: 'It's not fair! She gets to eat pizza - and I don't.'

Danley, who was in the Philippines at the time of the attack, returned to the United States late on Tuesday, arriving in Los Angeles from Manila. She could reveal more clues about Paddock's motives when investigators interview her.

Paddock was known to have previous relationships, none of them recent.

Court records show that he got married in 1977. The couple separated in 1979 before their divorce was finalized in 1980 in Los Angeles County.

Five years later, Paddock married again, separating in 1989 and divorcing in 1990, also in Los Angeles County, according to court and public records.

In both cases, divorce papers cited irreconcilable differences.
