Possible 2nd susp in Vegas

INVESTIGATORS acknowledge at least one other person could have known about Stephen Paddock’s plan to execute dozens of country music concertgoers in Las Vegas.

Clark County Undersheriff Kevin McCahill, after declaring law enforcement had already chased more than 1,000 leads, said Friday they remained unsure if someone had advance word of the carnage.

“I can tell you this: We are very confident that there was not another shooter in the room,” McCahill said. “What I cannot confirm to you, and what we continue to investigate, is whether anybody else might have known about this incident before he carried it out.”

There remained one indicator a second person may have been inside the 32nd floor hotel suite at the Mandalay Bay Resort and Casino: a phone charger that failed to match any of Paddock’s devices, NBC News reported.

Investigators also believe Paddock may have hired a hooker in the days before the shooting, according to the Associated Press. Agents are interviewing prostitutes as part of their search for a motive.

A review of “voluminous amounts” of video from Mandalay Bay security cameras did not resolve the question about prior knowledge regarding the methodical plan that became the deadliest mass shooting in modern U.S. history.

McCahill said the investigation was not entirely in vain — but it still failed to answer the biggest question: Why?

“While some of it has helped create a better profile into the madness of the suspect, we still do not have a clear motive or reason why,” he said.

Authorities have yet to turn up a manifesto, a social media post or anything else offering an explanation of the Sunday night shooting.

McCahill refuted a report that a hotel key card was used to enter Paddock’s room at a time when the millionaire gambler’s car was gone from the hotel garage.

The report suggested a second person had access to the suite where Paddock, 64, made his final stand with a cache of 23 weapons and thousands of rounds of ammo.

Paddock’s arsenal included 1,000 rounds of tracer bullets typically used in nighttime military assaults. The casino regular and video poker enthusiast purchased the illuminating ammunition three weeks before the shooting rampage that left 58 people dead at the Route 91 Harvest Festival on the Las Vegas strip, the Associated Press reported.

It was unclear if Paddock fired any of the tracers from his perch 1,200 feet away from the concert site. The bullets leave a bright-colored trail in their wake, improving a shooter’s accuracy in the darkness.

Paddock purchased the bullets from a private gun dealer after they met at a Phoenix gun show, according to the AP.

NBC reported that Paddock’s 2015 tax return showed $5 million in income, most of it from gambling profits.
