Las Vegas shooter Stephen Paddock wired $100,000 to an account in his live-in girlfriend’s home country, the Philippines, in the week before he unleashed the worst mass shooting in modern U.S. history , according to multiple senior law enforcement officials.

But while officials have confirmed that Marilou Danley was in the Philippines on Sunday when Paddock opened fire on a crowd attending a country music festival on the Las Vegas Strip , it was not known whether the money was for her or her family or for another purpose.

Danley, 62, who had traveled to Hong Kong on Sept. 25, could fill in some of the blanks when she returns to the United States on Wednesday, the officials said. Her arrival airport was not known.
