Criminal investigation

Police say Las Vegas gunman planned ‘extensively,’ used cameras to monitor officers as they approached

People close to the investigation also said that in the weeks before the attack, Paddock transferred a large amount of money — close to $100,000 — to someone in the Philippines, possibly his girlfriend. The significance of that development was not immediately clear, though investigators said they were interested in probing Paddock’s finances and his avid interest in high-stakes gambling.

The girlfriend, Marilou Danley, returned to the United States from the Philippines Tuesday night and was met at Los Angeles International Airport by FBI agents, according to wire reports. Investigators considered her a “person of interest,” Lombardo said. Sen. Dean Heller (R-Nev.) said that police are eager to talk to her, as Paddock “doesn’t meet any profiles” and the “best lead is through this girlfriend.”

“They don’t know a lot about who the girlfriend is and why she left the country a week prior to the shooting,” said Heller, who has been briefed by authorities. “She is someone they need to have this discussion with to better understand the shooting and what his thought process was.”
