Las Vegas shooter Stephen Paddock wired $100,000 to an account in the Philippines the week before he opened fire on a concert, multiple senior law enforcement officials told NBC News.

Paddock’s girlfriend, 62-year-old Marilou Danley, was in the Philippines, her native country, Sunday when Paddock began firing from the 32nd floor of the Mandalay Bay Hotel in Las Vegas. It remains unclear whether the money was intended for Danley, her family members, or for some unknown purpose.

The pair lived together in Mesquite, Nevada, and investigators believe that they began seeing each other in the spring of 2017.

Authorities maintain that Danley, who is scheduled to return to the U.S. for questioning Wednesday, did not participate in planning the attack.

“We have had conversations with her and we believe her, at this time, not to be involved. But obviously that investigation will continue,” Clark County Sheriff Joe Lombardo said. “She was not with [Paddock] when he checked in. We have discovered he was utilizing some of her identification.”

The Islamic State claimed responsibility for the attack Monday morning, but authorities insist that early investigations have yielded no corroborating evidence linking Paddock to foreign terror groups.
