No one, except Marilou, because Steve is not here to talk anymore. Still, one sister hoped that her perspective could provide some clues as to what happened.
Danley landed Tuesday at Los Angeles International Airport, a law enforcement source told CNN. Danley was allegedly in the Philippines during the attack and was met by Federal Bureau of Investigation agents upon her arrival at LAX. She had traveled to Hong Kong and Manila in the days before Paddock's attack.
"But obviously that investigation will continue", Clark County Sheriff Joe Lombardo said.
"She didn't even know that she was going to the Philippines, until Steve said "Marilou, I found you a cheap ticket to the Philippines", one of the women told NBC's Australian partner, Channel 7.
Adding more intrigue to the case is the news, confirmed to CNN by a USA law enforcement source, that Paddock recently wired $100,000 to the Philippines.
He had no criminal record and was not known to police, who have yet to state his motives for the mass shooting, the worst in U.S. modern history. His relentless gunfire - police say he fired for nine to 11 minutes after the first 911 call - left 58 people dead.
Footage from inside the hotel also revealed Mr Paddock had set up a camera on what appeared to be a room service cart in the hotel hallway to warn him when police were getting close.More news: Trump Administration Waives Shipping Restriction For Puerto Rico

However, no terrorist links have been confirmed and officials were earlier keen to play down the notion that Paddock was working with anybody.
As for his girlfriend, travel records obtained by ABC News show Danley, who uses an Australian passport, traveled to her home country of the Philippines on September 15.
Foreign Minister Julie Bishop said U.S. authorities contacted Australian officials to help locate her.
Paddock checked into the Mandalay Bay Hotel on 28 September, reportedly using some of Ms Danley's identity documents. It's unclear when the couple met. Danley's LinkedIn profile says that she is a "high-limit hostess" at a Vegas casino.

The 62-year-old former Queensland resident, who left Australia in 1989 and lived with Paddock in Nevada, has since been escorted to Las Vegas.
"This is a horrific event, and our hearts and prayers go out to everyone impacted by this awful act", Waltrip said.
"I reiterate he has no knowledge of Mr. Paddock or any knowledge as to why Mr. Paddock would do such a disgusting terrible thing", his daughter said.
