VEN (LAS VEGAS) — Las Vegas gunman, 64-year-old Stephen Paddock, who killed 58 and wounded over 500 people in the worst mass shooting in American history, remains an enigma.

The reclusive, retired multi-millionaire — who was a high-roller gambler in Las Vegas and a Platinum Club member at the Mandalay Bay Hotel where the shooting took place  — gave no outward signs that he was seething with rage and discontent.  And family and friends — even casual acquaintances — are shocked that he could have committed such a heinous crime.

Like clockwork, the usual bizarre conspiracy theories have begun surfacing on the Internet — everything from other shooters on other floors, to Mr Paddock being somehow framed and set up as a patsy — all of which are being vigorously denied by authorities.

Mr Paddock’s Filipino girlfriend, Marilou Danley, 62, who was out of the country at the time of the shooting, arrived in LAX Tuesday night for questioning.

According to anonymous sources, Ms Danely initially told authorities that “Stephen Paddock is the kindest, bravest, warmest, most wonderful human being I’ve ever known in my life,” and refused to comment further.

She has been taken into custody for additional questioning.

Meanwhile, VEN has learned that on the Friday night before the shooting, Mr Paddock left a high-stakes blackjack table at the Mandalay Bay casino after winning $120, 000.00.

“It was so strange,” another regular at the casino, who was sitting next to Mr Paddock at the time, told VEN‘s Senior Correspondent Lester Diamond Tuesday.

“This guy, Paddock, he splits two aces.  That’s 60 grand a hand. The dealer hits him with two face cards.  Two identical Queen of Diamonds.  The place went crazy!  All these chips are being pushed over to him, and he was just sitting there, with this glassy-eyed expression, staring straight ahead.

“It was f***ing weird.

“Then he just gets up, and he walks away!  He left over 120 grand worth of chips on the table!  The dealer had to signal the floorwalker, who went running after him!”
