LAS VEGAS – The Latest on the mass shooting in Las Vegas (all times local):
Lawyers who filed a lawsuit over the response to the Las Vegas massacre question why police and hotel and concert security officers didn't act more quickly to stop the gunman.
The lawyers held a news conference Wednesday alongside families of victims in the Oct. 1 shooting that killed 58 concert-goers and wounded hundreds more.
The attorneys want to know why six minutes passed without a police response from the time gunman Stephen Paddock strafed a hallway of the Mandalay Bay hotel with 200 rounds until he started killing people at the concert.
They also are perplexed about how Paddock was able to bring more than 20 rifles into his room without being detected.
Attorney Chad Pinkerton said authorities "should have done a better job and that's what this lawsuit is about."
A maintenance worker says he immediately notified hotel dispatchers after a gunman sprayed a hotel hallway with bullets before shooting into a crowd at a Las Vegas music festival.
Stephen Schuck told NBC News on Wednesday that he was checking on a jammed door on the 32nd floor of the Mandalay Bay hotel on Oct. 1 when he heard gunshots.
He says he saw security guard Jesus Campos pop out from an alcove and was warned to take cover.
As he tried to take cover, bullets began flying in the hallway, whizzing right past his head. Schuck says he used his radio to alert hotel dispatchers that someone was firing a rifle in the hallway.
Police said Monday that gunman Stephen Paddock shot at the men about six minutes before he opened fire on the concertgoers, killing 58 people. They initially said he was already firing on the crowd when he paused to shoot through his door at the security guard.
Another wrinkle has been added to the investigation into the Las Vegas massacre after a spokeswoman for the hotel where the gunman was a guest raised questions about the latest timeline of events provided by police.
MGM Resorts International spokeswoman Debra DeShong said the company believes "what is currently being expressed may not be accurate."
She didn't elaborate, but the statement came a day after police revised their chronology of events for the night of Oct. 1, when gunman Stephen Paddock opened fire from the 32nd floor of the Mandalay Bay hotel and killed 58 people.
Police initially said Paddock stopped firing on the crowd to shoot through his door and wound a Mandalay Bay security guard. On Monday, they said the guard actually was wounded before Paddock started the massacre.
