The authorities are planning to put up billboards in Las Vegas to seek more tips as they investigate the deadliest mass shooting in modern US history.
Mr Campos was struck in the leg when Paddock fired 200 rounds into the hallway, but managed to escape and inform authorities where the gunfire was coming from.
"Because Paddock doesn't fit in, he's all the more intriguing". He was a millionaire.
Of the 58 people killed during the massacre, 36 were women and 22 were men.
Paddock bought the.308-caliber and.223-caliber tracer ammunition from a private buyer he met at a Phoenix gun show, a law enforcement official not authorized to comment on the investigation said on condition of anonymity.
According to the Clinton County records, Paddock's birth father was Benjamin Paddock, of Sheboygan, Wisconsin, a fact which also matches biographical reports on the gunman. Representatives said Paddock won about $300.
However, that may change as the investigation unfolds, he said. "Enough to get a meal". And they're also celebrating their heroes. At some point, he ate two meals with his winnings. Paddock's girlfriend, Marilou Danley, accompanied him on nine of the cruises.
Investigators were unsure of the significance of the hotel bookings and are trying to determine if they were ominous signs of the horror to come or the meaningless actions of a man with the financial means to fly around the country.

A frustrated Kevin McMahill, the undersheriff at the Las Vegas Metropolitan Police Department, asked the public to avoid the constant rumor and speculation as to Paddock's motives, which he said were understandable but unhelpful.
On Monday, officers recovered 19 firearms, explosives and ammo from Paddock's home in Mesquite, Nevada, hours after discovering 23 guns in his hotel room.
"There are states in the country where there's a lot of hunting, outdoor activities".
"What is going on in our town?"
According to the officials, it is unclear whether he told about his plan to anyone before shooting. Cassell said he wondered.
Paddock's aversion to human contact, the real estate broker said, was in part why he preferred playing video poker, a type of gambling that doesn't require interaction with other players.
In general, mass killers, almost all of whom are young men, are motivated by some combination of paranoia and mental illness or financial and social problems, he said. The cell phones kept ringing and ringing. And thousands of people turned out to honor him.
Meanwhile, as lawmakers in Washington again took up the issue of gun regulation, the National Rifle Association on Thursday called for a government review on the legality of "bump stock" accessories that modify semiautomatic weapons to fire at nearly fully automatic speed. "And that looked straight, like, out of a movie, you know?"
