Las Vegas gunman fired into hall, crowd at about same time, hotel says

The owner of the hotel from which a gunman carried out the deadliest mass shooting in modern U.S. history on Thursday provided a new version of the timeline, suggesting there was no time for hotel staff to warn police.

Stephen Paddock opened fire on Mandalay Bay hotel security guard Jesus Campos and the crowd attending a concert nearby at the same time or within 40 seconds of each other, MGM Resorts International said in a statement.

Police have still not determined a motive for the shooting.

That account differed from the updated timeline Las Vegas police provided on Monday, when they said Campos had been shot six minutes before Paddock, 64, opened fire on the crowd from his 32nd-floor suite and killed 58 people on Oct. 1. MGM said on Tuesday the revised police timeline might not be accurate.

A Las Vegas Metropolitan Police Department spokesperson, Officer Larry Hadfield, said the police would have no immediate comment on the hotel's Thursday statement. The Las Vegas office of the Federal Bureau of Investigation could not immediately be reached for comment.

Clark County Sheriff Joseph Lombardo, who oversees the police department, on Wednesday defended the speed of the police response in an interview with the Las Vegas CBS television affiliate.

"No matter what that timeline was, the response was as quick as possible. I don't think the response could have been any faster," Lombardo said in a video posted on the station's LasVegasNow.com website.

The revised timeline police provided on Monday had raised new questions, including why Paddock ceased firing on concertgoers once he began, and whether hotel security and police co-ordinated as well as first believed.

MGM, which owns the Mandalay Bay hotel, said the 9:59 p.m. time when police said Campos was shot was derived from a hotel report created manually after the fact without the benefit of information the hotel now has.

"We are now confident that the time stated in this report is not accurate," MGM said. "We know that shots were being fired at the festival lot at the same time as, or within 40 seconds after, the time Jesus Campos first reported that shots were fired over the radio."

A maintenance worker, Stephen Schuck, also called for help on his radio, asking a dispatcher to call the police because someone was shooting a rifle on the hotel's 32nd floor.

Las Vegas police officers were with armed hotel security officers in the building when Campos, who was checking an open-door alarm on that floor, first reported that shots were fired over the radio, MGM said. Both groups immediately responded to the 32nd floor.

The police have said they assembled a SWAT team and burst into Paddock's room to find him dead, 81 minutes after the security guard was shot (if that happened at the disputed time, 9:59).

"We will continue to work with law enforcement as we have from the first moments of this tragedy as they work toward developing an accurate timeline," MGM said.

MGM's new timeline is a blow to lawyers representing some of the victims, whose claims depended heavily on the hotel's allegedly delayed response following the shooting of Campos. A lawsuit filed in Nevada state court on Tuesday on behalf of a California woman injured in the shooting had alleged the hotel acted negligently by responding too late.

Neama Rahmani, a Los Angeles lawyer representing some of the victims, said in an email to Reuters on Thursday that MGM may have acted quickly, "but the question of whether reasonable precautions were in place remains."

Still digging for a motive

FBI Director Christopher Wray said investigators haven't yet determined a motive behind the mass shooting but they're still digging.

"There's a lot of effort being put into unraveling this horrific act," Wray told reporters after a ribbon-cutting for the FBI's new Atlanta building. "We don't know yet what the motive is, but that's not for lack of trying, and if you know anything about the bureau we don't give up easy."

Also Thursday, a funeral was held for Erick Silva, a 21-year-old security guard at the festival who was shot in the head while helping people climb over a barricade to escape the gunfire. Dozens of fellow "yellow shirt" security guards were among the hundreds of mourners at the service, where Silva was hailed as a hero.

"We counted on him, and he didn't let us down," said his boss, Gina Argento.
