Law enforcement authorities say Marilou Danley, a woman initially described as a “person of interest” in the shooting in Las Vegas Sunday night, is not believed to have been involved with the attack.

Sheriff Joseph Lombardo of Clark County told reporters Monday that Danley was out of the country when Stephen Paddock began shooting from the 32nd floor of the Mandalay Bay Hotel and Casino.

"Marilou Danley is no longer being sought out as a person of interest," the Las Vegas Metropolitan Police Department said. "LVMPD detectives have made contact with her and do not believe she is involved with the shooting on the strip."

Lombardo said his department has spoken with Danley. He said authorities believe Paddock used Danley’s identification during his stay at the hotel. According to one media source, Danley is believed to be Australian and was described as a roommate of girlfriend of Paddock’s.

On Danley’s Facebook page, she describes herself as a “proud mom and grandma who lives life to the fullest”.
