What does Paddock's girlfriend say?

Analyzing Paddock's computer, cellphone and other electronic devices, Investigators have found no obvious ideological motive, no clear connection to extremists or activist groups or outward display of mental illness.

Paddock bought the.308-caliber and.223-caliber tracer ammunition from a private buyer he met at a Phoenix gun show last month, a law enforcement official not authorized to comment on the investigation said on condition of anonymity.

Officials say updates for people who left belongings in other areas of the festival grounds will be made public through news reports and on Twitter on @ClarkCountyNV, @LVMPD, @FBILasVegas and with the hashtags #1October and #VegasStrong.

When Paddock checked into the Mandalay Bay on September 28, he requested an upper-floor room with a view of the Route 91 Harvest music festival, according to a person who has seen hotel records turned over to investigators and spoke on condition of anonymity.

The wealthy real estate investor opened fire Sunday from his multistory perch onto the crowd below, killing 58 people and injuring nearly 400.

Investigators are also looking into whether Paddock planned a vehicle bombing after the attack.

The gunman who opened fire on thousands of concertgoers in Las Vegas late Sunday night had booked two rooms in Chicago earlier this summer overlooking Grant Park during Lollapalooza, according to a report from TMZ. "We owe it to the victims and the victims' families", McMahill said.

Clark County Sheriff Joseph Lombardo said it's hard to believe Paddock acted alone in the attack on the audience of an outdoor concert.

Paddock reportedly called Mandalay Bay's security twice to complain about loud music.

Apart from frequenting casinos, Paddock was also a regular in cruises and took about 20 trips to various foreign ports.

Investigators in Las Vegas are turning to the public in the search for clues as to what prompted 64-year-old gunman Stephen Paddock to to carry out the deadliest mass shooting in modern U.S. history.

A spokeswoman for the Blackstone Hotel, Emmy Carragher, says a person with the name Stephen Paddock reserved a room but never checked in.

Paddock, who officials believe had an escape planned, fatally shot himself as a SWAT team descended on his hotel room.

An unnamed law enforcement source confirmed the existence of the notes to CNN.

As US investigators search for the motive for Stephen Paddock's murderous assault in Las Vegas, a conflicting picture of his personality has emerged.

According to the Daily Mail, a Las Vegas prostitute, hired by Paddock, has claimed that they had violent sex session and that Paddock bragged that he had "bad blood" on account of his father, who at one time was on the FBI's most-wanted list.

McMahill told reporters that investigators reviewed hours of video from the casino, and that nothing points to the idea that Paddock had an accomplice.
