The Las Vegas shooter's girlfriend is back in the U.S., but she is not in custody.

Officials say Marilou Danley was in the Philippines during the time of the attack, but she arrived in Los Angeles Tuesday night and was immediately met by FBI agents. Detectives said Danley is considered a "person of interest" in the investigation.

A Philippines immigration spokeswoman said Danley had arrived in the Philippines on Monday, Sept. 15, from Hong Kong, nearly a week before her boyfriend, Stephen Paddock, killed 58 people and wounded 527 others in a mass shooting in Las Vegas at the Mandalay Bay Casino during a concert before he killed himself.

Paddock, a 64-year-old high-stakes gambler and retired accountant with Florida ties, killed himself before police stormed his 32nd-floor room.

Paddock's brother, Eric, who lives near the Waterford Lakes community near the University of Central Florida, said he's in shock over what happened and simply can't believe his brother would do something like this.

"Steve had nothing to do with any political organization, religious organization, no white supremacist (group), nothing as far as I know, and I've only known him for 57 years," Eric Paddock said.

In a break from talking with federal investigators at his Orlando-area home, he said Stephen Paddock lived in Melbourne until he helped him move to Nevada, where he loved to play high-stakes video poker.

Philippines immigration bureau spokeswoman Antonette Mangrobang said authorities there had been working with U.S. officials.

“From the very beginning, we have been providing them necessary information that would aid their investigation,” Mangrobang said.

Paddock transferred $100,000 to the Philippines in the days before the shooting, a U.S. official briefed by law enforcement but not authorized to speak publicly because of the continuing investigation told The Associated Press on condition of anonymity.

Investigators are still trying to trace that money and also looking into a least a dozen financial reports over the past several weeks that said Paddock gambled more than $10,000 per day, the official said.

As for what may have set Paddock off, retired FBI profiler Jim Clemente speculated that there was “some sort of major trigger in his life — a great loss, a breakup, or maybe he just found out he has a terminal disease.”

Clemente said a “psychological autopsy” may be necessary to try to establish the motive. If the suicide didn’t destroy Paddock’s brain, experts may even find a neurological disorder or malformation, he said.

He said there could be a genetic component to the slaughter: Paddock’s father was a bank robber who was on the FBI’s most-wanted list in the 1960s and was diagnosed a psychopath.

“The genetics load the gun, personality and psychology aim it, and experiences pull the trigger, typically,” Clemente said.

Paddock had a business degree from Cal State Northridge. In the 1970s and ’80s, he worked as a mail carrier and an IRS agent and held down a job in an auditing division of the Defense Department, according to the government. He later worked for a defense contractor.

He had no known criminal record, and public records showed no signs of financial troubles. In addition, the FBI stated that there were no connections between Paddock and any terrorist groups, although ISIS claimed responsibility for the shooting.

For the shooting to be considered an act of terrorism, a motive has to be established and the attack was done to influence a political change.

While Paddock’s motive has proved elusive, investigators have found no shortage of evidence of how Paddock carried out the elaborate attack.

He planned the massacre so meticulously that he even set up cameras inside the peephole of his high-rise hotel room and on a service cart outside his door, apparently to spot anyone coming for him, authorities said.

Investigators also found a computer and 23 guns with him at the hotel, along with 12 “bump stock” devices that can enable a rifle to fire continuously, like an automatic weapon, authorities said. Nineteen more guns were found at Paddock’s Mesquite home and seven at his Reno house.

Authorities released police body camera video that showed the chaos of the attack as officers tried to figure out the location of the shooter and shuttle people to safety. Amid sirens and volleys of gunfire, people yelled “they’re shooting right at us” while officers shouted “go that way!”

Clark County Undersheriff Kevin McMahill said the shooting spanned between nine and 11 minutes.
The cameras Paddock set up at the Mandalay Bay hotel casino were part of his extensive preparations that included stockpiling nearly two dozen guns in his room before opening fire on the concert below.

McMahill said the cameras included one in the peephole and two in the hallway.

“I anticipate he was looking for anybody coming to take him into custody,” Lombardo said.

During the Sunday night rampage, a hotel security guard who approached the room was shot through the door and wounded in the leg.

“The fact that he had the type of weaponry and amount of weaponry in that room, it was preplanned extensively,” the sheriff said, “and I’m pretty sure he evaluated everything that he did and his actions, which is troublesome.”

President Donald Trump and the First Lady are headed to Las Vegas on Wednesday. They plan to meet with people who were injured and family members of those who were killed and first responders.
