The Las Vegas gunman Stephen Paddock, 64, who massacred 59 people and injured over 500 people on Sunday in Las Vegas, wired $100,000 to a bank account in the Philippines, which is his live-in girlfriend's home country.

He sent this money to the bank account just a week before carrying out the attack. The money is being investigated to ascertain if it went into his girlfriend's account and if she was involved in any way in the killing and find out what she may know.

His live-in girlfriend Marilou Danley, 62, who was in the Philippines when her boyfriend committed this heinous act is now in the US.

On Tuesday, Las Vegas Sheriff Joseph Lombardo confirmed Danley is a person of interest in the investigation again.

The FBI contacted Danley and asked her to return to the US so she could be questioned because she is now a person of interest in the investigation. She has since returned to the US and was met at the airport in LA by the FBI.

Danley reportedly told the Police that she only started dating Paddock early this year but photos obtained by DailyMail.com on Tuesday showed them in the Philippines with her family in 2013 and in a Reno nightclub with the woman's hotel and casino colleagues in 2014.
