Mass Murderer Stephen Paddock Girlfriend Returns to U.S. for Questioning

Stephen Paddock's girlfriend -- a person of interest in the Vegas slaughter -- returned to the U.S. Tuesday night for what will almost certainly be days of questioning.

Marilou Danley flew from the Philippines to LAX where she was met by authorities. MSNBC got these images of Danley being escorted out of the Bradley International Terminal in a wheelchair.

Authorities want to know what she knew about Paddock's elaborate plan to spray the country music festival with bullets. Law enforcement will also grill her over the $100,000 Paddock reportedly transferred to the Philippines days before the shooting.

He also has high praise for Jimmy Kimmel, who he has developed a voice more powerful than the President's or members of Congress ... first on the subject of health care, and now gun control.

Mass Murderer Stephen Paddock Brother Off the Rails In Bizarre Interview

The brother of mass murderer Stephen Paddock lost it Tuesday during a bizarre, rambling interview.

Eric Paddock spoke with CBS News and broke down, unable to talk for a time, before his thoughts about his brother meandered.

He says his family is torn apart over the deeds of his brother, and this isn't the Stephen they knew.

Eric says his brother transferred $100k to the Philippines for legit reasons ... to care for his girlfriend. Authorities say she's still a person of interest, but Eric thinks his brother manipulated her to leave the country so she wasn't around when he fired into the Vegas crowd.

Eric also says his brother was rich and generous with his money, sometimes spending thousands of dollars on sushi for friends and relatives.

He then went into a rant about his mom. It's all over the place.

Wayne Newton doesn't think the shooting massacre in Las Vegas will dim the lights in venues along the strip ... but he says Sin City's performers gotta do what they do and power through the grief.

Wayne -- a Vegas staple in live entertainment -- came on "TMZ Live" Tuesday to dish on whether Vegas would have a hard time coming back to full form after Stephen Paddock gunned down 59 people and injured hundreds more from the 32nd floor of the Mandalay Bay hotel.

The Midnight Idol doesn't seem too worried about that, 'cause he says Vegas is still one of the safest places around despite the massacre. But he's putting the local showstoppers on notice here too.

Basically ... places, everyone.

Stephen Paddock Brother Says ... He was a Typical Vegas Guy

Stephen Paddock's brother Eric Paddock seemed dumbfounded by the monstrous actions of his sibling.

Eric just appeared on CBS News and said his brother was not an avid gun collector. He had no idea where Stephen Paddock got automatic weapons ... no idea at all.

Eric was in the dark, because cops have already searched Stephen Paddock's home and it appears they found a cache of weapons and ammo. The recently-built house was well kept in the upscale retirement community.

Eric painted his brother as a normal guy living in Nevada ... eating burritos and gambling.

He was also relieved his brother didn't harm his girlfriend. He actually seems unsure whether she was his girlfriend or whether they were secretly married.

Jason Aldean was performing when the shooting began. He and his band were able to scramble to safety as bullets reportedly ricocheted onto the stage.

At least one off-duty police officer is among the fatalities.

Police in Las Vegas are responding to a mass shooting at the Mandalay Bay Resort, where multiple people are reportedly injured ... and multiple shooters are suspected.

Videos from social media started pouring in late Sunday night showing multiple rounds being fired from what sounds like a rooftop or from somewhere up high. People are taking cover and running for their lives.
