A California woman remains missing days after she was reportedly spotted alone at a local casino on Valentine’s Day.

In a Facebook post, the El Dorado County Sheriff’s Office said Brooke Harris, 48, was last seen in person by her daughter last Wednesday evening and that Harris had spoken to her husband on the phone early Thursday. Security cameras at the Red Hawk Casino in Placerville filmed her alone at around 4:30 p.m. Thursday before she vanished.

Police said Harris’ cell phone was located at her home, adding that there’s no indication foul play was involved in her disappearance. They went on to reveal that they believe she left on her own accord.

“We have investigated Brooke’s family and have found no evidence to suggest that anyone was involved in her disappearance. The family has been completely cooperative throughout this entire investigation,” they wrote.

The Sacramento Bee reported that law enforcement’s revelation came following news that Harris was a registered nurse who was fired in 2014 and surrendered her license in 2016—both of which came after she admitted to drinking vodka while working in hospice care.

Harris reportedly petitioned the Board of Registered Nurses to have her license reinstated in April of last year. The board president reinstated her license on January 10 and ordered a three-year probation period to begin on February 8, according to documents.

Police Sergeant Anthony Principe told The Bee that they knew of the public records but didn’t disclose when they learned of them.

“We are aware of the public documents. We are aware of everything that’s been circulating,”  Principe said Wednesday.

On Tuesday, the El Dorado County Sheriff’s Office posted images of Harris’ car, a gray 2015 Toyota Highlander with California license plates X1379. They asked anyone with information regarding her whereabouts to call them at 530-621-6600.
