The Latest on the final report into the Oct. 1 mass shooting in Las Vegas that killed 58 people (all times local):

6 p.m.

A survivor of the deadliest mass shooting in modern U.S. history says it was gun-wrenching that Las Vegas police didn't determine a motive for the rampage.

Megan O'Donnell Clements of Wilmington, Delaware, told The Associated Press on Friday that not knowing why Stephen Paddock opened fire on the concert she attended in October is "kind of horrifying" and that she lacks closure.

Police released their final report from a 10-month investigation into the shooting that killed 58 people and injured hundreds of others.

It says Paddock became increasingly unstable and distant from loved ones but that there was no troubling behavior that would have led to a call to law enforcement.

Police in Las Vegas say the gunman who carried out the deadliest mass shooting in the nation's modern history also fired armor-piercing incendiary bullets at nearby aviation fuel tanks.

A final investigative report of the Oct. 1 shooting was released Friday. It says gunman Stephen Paddock fired eight incendiary rounds at a fuel tank at the city's airport. Two bullets hit the tank, but it didn't explode.

A timeline says those shots were among the first of 1,057 that Paddock fired for 11 minutes from the windows of the 32nd floor of the Mandalay Bay resort into a concert crowd below.

Police who entered the room more than an hour later found Paddock dead of a self-inflicted gunshot next to a handgun as well as 23 assault-style weapons strewn about.

Those who knew the gunman who opened fire at a country music festival on the Las Vegas Strip last year painted an inconsistent picture for investigators of a successful gambler who enjoyed traveling but avoided germs and hand-shaking.

The people interviewed by investigators in a report made public Friday said Stephen Paddock was very detail-oriented but had poor-health and an unkempt appearance. They also said he was not interested in attention or flashy items but always wanted to be the best.

Paddock's ex-wife Peggy Paddock told investigators her former husband grew up with a single mom in a financially unstable home and felt a need to be self-reliant. She says Stephen Paddock was not interested in drawing attention to himself and did not buy flashy clothes, jewelry or cars.

His youngest brother Eric Paddock called his brother a narcissist and said he needed to be seen as important.

Investigators say the brother described Stephen Paddock as someone who "always wanted to be the best and known to everyone."

Friends and family said he did not appear violent and or to be abusing drugs or alcohol.

Las Vegas police said in a report on the shooting made public Friday that Paddock told his girlfriend Marilou Danley that "he believed President Trump would do something to stop illegal immigration."

The report says Paddock did not belong to any political organizations, did not comment on gun control did not display any racial bias.

Detectives investigating last year's mass shooting in Las Vegas conducted interviews with valet attendants, security officers, housekeepers and other workers of the Mandalay Bay casino-resort who interacted with gunman Stephen Paddock at the Mandalay Bay casino-resort before he opened fire on a country music festival.

Two bellmen who helped Paddock move luggage to his room during his stay at the property on the Las Vegas Strip told authorities none of the items they moved were unusually heavy.

One told authorities Paddock requested the use of back or service elevators, which the employee explained is not uncommon for VIP guests to do.

Authorities have said Paddock amassed an arsenal of weapons in his 32nd floor suite.

The report shows a housekeeper told authorities she saw an open laptop surrounded by papers when she was cleaning the room, but never saw guns or bullets in the room.

Detective Trever Alsup's comments were in a final report made public Friday into the rampage by Stephen Paddock, who rained gunfire from a 32nd floor hotel-casino suite onto a country music festival, killing 58 people.

The claims about Paddock's rants were among redacted witness accounts released by the authorities in May under court in a public records case by media including The Associated Press.

One man told police he heard the man say, "Somebody has to wake up the American public and get them to arm themselves," and that, "Sometimes sacrifices have to be made."
