LAS VEGAS (AP) - 12:35 p.m.
A U.S. official says the Mandalay Bay hotel casino didn't notify police that gunshots had been fired inside the tower until after a gunman opened fire on the crowd outside at a country music festival.
The official, who was briefed by law enforcement, wasn't authorized to discuss the matter publicly and spoke to The Associated Press on condition of anonymity Thursday.
The disclosure means there was a delay of some six minutes in summoning police to the scene as the gunman began firing in the deadliest mass shooting in modern U.S. history.
Two hotel employees had called for help and reported gunman Stephen Paddock sprayed a hallway with bullets and struck an unarmed security guard in the leg six minutes before Paddock opened fire on the crowd, killing 58 people and injuring nearly 500 others.
Nevada's two U.S. senators want mortgage payment relief for family members of victims of the Las Vegas massacre as they deal with medical and funeral costs.
Republican Sen. Dean Heller and Democratic Sen. Catherine Cortez Masto sent a letter Thursday to lenders and regulators asking them to ease the burdens on those affected by the Oct. 1 shooting at the Route 91 Harvest Festival.
The senators asked lenders not to initiate or finalize foreclosures and to work with the homeowners to come up with plans like loan modifications if they miss payments.
Heller and Cortez Masto say the families should not have to worry about financial situations that exacerbate the "tremendous stress caused by this senseless tragedy."
A hotel-casino in Reno, Nevada, has canceled a gun show scheduled this weekend in the aftermath of the mass shooting in Las Vegas.
The Rocky Mountain Gun Show had been scheduled to run Friday through Sunday at the Grand Sierra Resort.
Resort officials said in a statement that the Reno stop for the event that tours the western United States has been canceled out of respect for the victims of the killings.
Dozens of people were killed and hundreds injured when Stephen Paddock opened fire from the 32nd floor of The Mandalay Bay hotel-casino on Oct. 1.
