The Latest on the shooting in Las Vegas last October that left 58 people dead and hundreds injured on the Las Vegas strip (all times local):

3:35 p.m.

An 81-page police report made public Friday offers a glimpse at Las Vegas shooter Stephen Paddock's internet searches and a timeline of his activities ahead of the deadliest mass shooting in modern U.S. history.

It doesn't say what drove Paddock to kill 58 people and injure 851 at the Route 91 Harvest Festival on Oct. 1.

Police say they found Paddock shuttled between a rented downtown condominium with a view of one open-air music festival and the casino resort from which he unleashed carnage at a separate Las Vegas Strip concert venue.

The FBI and U.S. attorney's office in Las Vegas are not providing details about whether a federal grand jury is hearing evidence in a case spun off of the Oct. 1 mass shooting that became the deadliest in modern U.S. history.

Spokeswomen for both agencies declined comment Friday after Clark County Sheriff Joe Lombardo said the FBI was investigating "an individual of federal interest" other than the shooter, Stephen Paddock.

Lombardo also says a federal grand jury is hearing evidence in a case spun off from the Oct. 1 mass shooting.

Paddock killed himself after killing 58 people and injuring hundreds, and Lombardo said no criminal charges are being considered against Paddock's girlfriend, Marilou Danley.

The sheriff did not identify the person under federal investigation or say what charges the person might face.

Lombardo told reporters that all the guns Paddock amassed were legally obtained.

But he noted that investigators found "numerous" images of child pornography on Paddock's computers.

The sheriff in Las Vegas now says 851 people suffered injuries directly related to the Oct. 1 mass shooting that became the most deadly in modern U.S. history, including 422 who were hurt by gunfire.

The new overall injury figure provided Friday by Clark County Sheriff Joe Lombardo is significantly higher than the number of about 550 hurt that was provided last October.

Lombardo provided no further details about the injured or how people were hurt other than by gunfire.

In the days after the shooting, some people reported suffering injuries in the hectic rush by thousands to flee the gunfire.

Fifty-eight people were fatally shot before the shooter, Stephen Paddock, killed himself.

A preliminary police report says the bodies of 31 were found in or immediately outside a concert venue across Las Vegas Boulevard from the Mandalay Bay resort.

That's where the report says Paddock amassed an arsenal of assault-style weapons and opened fire into a concert crowd of about 22,000 at the annual Route 91 Harvest Festival.

Clark County Sheriff Joe Lombardo told reporters Friday that no one may be charged with any crimes directly stemming from the shooting that killed 58 people and injured hundreds.

Authorities say Las Vegas gunman Stephen Paddock conducted extensive online searches for police and SWAT tactics and searched for other potential targets before he carried out the deadliest mass shooting in modern U.S. history.

Clark County Sheriff Joseph Lombardo said Friday that investigators believe Paddock had searched for several other public venues and took photographs of other potential sites.

A preliminary report about the shooting says Paddock searched for outdoor concert venues, the number of attendees at other concerts in Las Vegas and the number of people who go to the beach in Santa Monica, California.

The report also says Paddock also searched for information about several other hotels in Las Vegas.

Investigators say they have still not determined why Las Vegas mass shooter Stephen Paddock opened fire from his high-rise hotel suite, killing 58 people and injuring hundreds.

Clark County Sheriff Joe Lombardo told reporters Friday that investigators believe Paddock acted alone in the Oct. 1 shooting at the Mandalay Bay casino-hotel.

Lombardo says he does not expect charges to be filed against Paddock's girlfriend, Marilou Danley, who had been previously called a person of interest in the case.

Lombardo said the investigation found that Paddock had possessed child pornography.

With questions still unanswered about the shooter's motive and whether he had help, Las Vegas police are due to provide a public update Friday about the investigation of the Oct. 1 shooting that left 58 people dead and hundreds injured on the Las Vegas Strip.

Clark County Sheriff Joe Lombardo's briefing comes three days after a lawyer for the police department asked a Nevada state court judge to keep search warrant documents sealed because charges are still being investigated. The judge agreed to wait until at least next week.

A department spokeswoman said criminal charges could relate to items discovered in the service of warrants at homes, vehicles, cellphones, internet and email accounts belonging to the shooter, Richard Paddock, and his girlfriend, Marilou Danley.

Lombardo is the elected head of the metropolitan police department. His last media briefing about the worst mass shooting in modern U.S. history was Oct. 13, following several days of shifting timelines and accounts. The sheriff has expressed frustration about speculation and theories that have grown about the shooting and an investigation that he compared with solving a puzzle.
