The ever-changing story surrounding the Las Vegas shooting just took another twist.

The Mandalay Bay hotel is now disputing the police timeline.

And it’s raising some ugly questions.

According to the police, there was a six minute gap between the time the gunman sprayed a hallway with 200 rounds in a confrontation with a hotel security guard and when he began his massacre on fans at a country music festival.

The management group of the Mandalay Bay hotel is refuting this account.

They contend the gunman began firing upon concert goers within seconds of shooting their employee.

The Los Angeles Times reports:

“The company that runs the Mandalay Bay Resort and Casino has disputed the timeline offered by Las Vegas police for the Oct. 1 mass shooting at the hotel, suggesting Thursday that very little time had elapsed between when gunman Stephen Paddock shot a hotel security guard and when he started firing on a concert crowd outside.

The police timeline indicates that six minutes elapsed after security guard Jesus Campos was shot outside Paddock’s hotel room door before Paddock fired his first shots at the crowd, but MGM Resorts International managers say they are “now confident” that the timeline is “not accurate.”

“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,” the company, which owns Mandalay Bay, said in a statement.”

But the Los Angeles Times reports the hotel’s statement raises even further questions because it only indicates when the security guard reported being shot, not when the gunman actually shot him:

“One crucial element missing from the hotel’s statement: What time Campos was shot, as opposed to what time he reported being shot.

The statement confirms that Campos, who was wounded in a leg after Paddock fired an estimated 200 bullets through his hotel room door, may have reported a gunman in the hotel sometime before the massacre began at 10:05 p.m.. It continues to raise questions about why it took police at least 12 minutes to reach the gunman’s floor when armed security and Las Vegas police were already in the building.

Pressure has mounted on Mandalay Bay to comment in recent days after Clark County Sheriff Joe Lombardo said Monday that the gunman shot Campos in the leg in the 32nd floor hallway at 9:59 p.m., a full six minutes before the massacre began.

An assistant sheriff told The Times on Tuesday that Campos called in the shooting before Paddock, 64, of Mesquite, Nev., started firing out his windows at the 21,000 people attending the Route 91 Harvest country music festival across the street.

MGM’s statement Thursday said company managers now believed the 9:59 p.m. time given for Campos’ shooting was not accurate. They said an erroneous report was given to investigators by Mandalay Bay “without the benefit of information we now have.”

As this investigation continues, the more information made available to the public, the more questions that are raised as opposed to answered.
