Las Vegas police now say no 6-minute gap between 1st shots and concert attack

Las Vegas Sheriff Joseph Lombardo told reporters Friday that police now agree with information released yesterday by MGM Resorts International and thatStephen Paddock shot and wounded a security guardin the Mandalay Bay hotel hallway aroundthe same time he began toshoot at the concert crowd.

It wasthe deadliest shooting in modern U.S. history.

On Monday, police had said Paddock sprayed 200 rounds into the hallway, woundingunarmed security guard Jesus Campos in the leg. They had said that six minutes laterhe unleashed his barrage of bullets on the festival crowd.

That six-minute gap raised questions as to whether police and hotel security could have acted more quickly to prevent casualties in the Oct. 1 attack.

Today,Lombardosaid he's "not in conflict" with MGM's statement yesterday. The hotel chain,which owns the Mandalay Bay, said Thursday that no more than 40 seconds passed between the time Campos called for help and Paddock opened fire on the crowd.

The timeline of events now has 9:59p.m. as the time Camposencountered a barricaded door adjacent to the door to Paddock's room. Lombardosaid Camposthen ascended to another floor in order to get to the hallway ofPaddock's 32nd-floor suite. About 10:05 shots were fired through the door, wounding Campos, Lombardosaid.

He said that is also the time that Paddock began his initial volley of fire from the hotel window. "No one is attempting to hide anything," Lombardotold reporters.

When police arrived on the 32nd-floor, at 10:17, Lombardosaid the firing had already ceased.

45 injured still in hospital

Police said Paddock killed 58 people. Today Lombardoput the number of injured at 546, with 45 still in hospital, some with critical injuries.

Lombardo, the Clark County sheriffwho oversees the LasVegas police, also said Paddock shot "with intent" at aviation-fuel tanks at McCarran International Airport, near the Mandalay Bay hotel.

He saidthe airport is reviewing safety measures and has contacted experts in fuel storage, but that there's a low probability aviation fuel could be ignited by gunfire.

Lombardo told reportersthat an autopsy of Paddock found nothing unusual during a visual inspection, but his brain was shipped to a facility for closer examination.

Authorities haven't determined why Paddock opened fire on the concert crowd before shooting himself. Some believed an autopsy could shed light on any medical problems that could have contributed.

FBI Special Agent in Charge Aaron Rouse said investigators have found no signs that Paddock had any extreme ideologies or connections with any groups.
