Investigators remain stumped about what drove gunman Stephen Paddock, a reclusive 64-year-old high-stakes gambler, to begin shooting at the crowd at a country music festival from his 32nd-floor hotel suite, killing 58 and wounding hundreds before taking his own life, the Associated Press reports. Clark County, Nv., Undersheriff Kevin McMahill said investigators had “looked at literally everything” and still do not have a clear motive. Investigators have chased 1,000 leads and examined Paddock’s politics, finances, any possible radicalization and his social behavior. Authorities have put up billboards asking anyone with information to contact the FBI. Investigators reviewed voluminous video from the casino and don’t think Paddock had an accomplice in the shooting, McMahill said. They want to know if anyone knew about his plot beforehand.
In their effort to find any hint of his motive, investigators were looking into whether he was with a prostitute days before the shooting, scrutinizing cruises he took and trying to make sense of a cryptic note with numbers jotted on it found in his hotel room. An official said investigators were interviewing call girls for information and looking into at least a dozen cruises Paddock took in the last few years, including one to the Middle East. It is unusual to have so few clues five days after a mass shooting. McMahill noted that in past mass killings or terrorist attacks, killers left notes, social media postings and information on a computer, or even phoned police.
