Recently details from the 1 October investigation are shedding light on what Marilou Danley had to say about her relationship with Stephen Paddock and his mental state.
The couple lived together at Paddock's house in Mesquite. Danley told investigators within the last year, Paddock seemed "distant" and that they were no longer intimate.
Paddock was also described as a "germaphobe" and had a strong reaction to smells.
Paddock also visited his doctor about a year before the shooting. His doctor described his behavior as "odd" and "having little emotion." The doctor suspected Paddock might be bipolar but said Paddock didn't want to discuss it with him further. He also said Paddock was fearful of medication and would often refuse to take them. Specifically, Paddock refused anti-depressants but accepted a prescription for anxiety medication.
During that same timeframe is when Danley said Paddock began buying firearms, something she thought was just his hobby.
Danley said the odd behavior continued when the couple visited the Mandalay Bay a month before the shooting. She said Paddock was acting strange and repeatedly looking through the window overlooking the Las Vegas Village venue and studying it from multiple angles.
At the time of the attack, Danley was in the Philippines. Paddock had wired her money, making her concerned about a possible break-up. She immediately cooperated with investigators after returning the U.S. after the shooting.
Initially a person of interest, investigators now say they don't believe Danley had any prior knowledge of the attack and wasn't involved. They're not expected to press any charges against her.
