A high-functioning autistic teenager who disappeared from her Arizona home one night in 2019 has been found alive in Montana.

Alicia Navarro, who was just 14 when she slipped out of her Glendale home, recently walked into a Montana police department and identified herself, Glendale police announced Wednesday.

‘She is by all accounts safe. She is by all accounts healthy, and she is by all accounts happy,’ Officer Jose Miguel Santiago said at a news conference.

It remains unclear how the teenager traveled more than 1,000 miles to a small town on the border of Canada, and if she was staying with anyone.

But her mother now says Navarro’s recent reappearance is proof ‘miracles do exist,’ as she urged family members of other missing people to have hope.

Navarro had not been heard from since she left her home in the early morning hours of September 15, 2019 while her parents were sleeping.

After hearing the news that an 18-year-old identified herself as the missing teenager, Glendale police said they immediately responded to the unspecified small town in Montana.

Officers said they were able to verify Navarro’s identity, and said she has been extremely cooperative with authorities.

‘I can’t even begin to express to you all the pride that I personally have in the men and women here at our police department,’ Santiago said.

‘Since her disappearance, our men and women here have been working tirelessly around the clock to not only bring closure to this family, but to make sure Alicia gets everything she possibly needs.’

He added that the girl ‘by all accounts appears to be in good spirits’ and ‘really just wants to move on with her life.

‘She is very apologetic to what she has put her mother though. And she understands that she has caused a lot of pain to her mother, and it was not intentional on her behalf, and she is hopeful that they can have a relationship.’

The police department is now investigating the case with the assistance of the US Marshals Office and the FBI.

‘I would ask patience, not only for us as law enforcement in this investigation, but patience for Alicia and her family,’ Glendale Police Department Lt. Scott Waite said Wednesday.

‘We can only imagine what she’s going through, mentally, emotionally, as well as her family, and as much as we’d like to say this is the end, this is probably only the beginning of where this investigation will go.’

Over the years, Navarro’s mom, Jessica Nunez, partnered with various private investigative services, put up billboards, appeared on television programs and used social media in her efforts to find her daughter

Navarro went missing just one week before her 15th birthday, leaving her mother a handwritten note in her bedroom saying she would come back home.

A few days prior, Arizona Republic previously reported, the girl had asked her mother, Jessica Nunez, if she could stay home from school.

Nunez agreed, figuring her daughter was nervous about starting classes at Bourgade Catholic School in Phoenix.

The mother-daughter duo then spent the next day visiting a chocolate factory, and Nunez said her daughter seemed happy.

But that night, Navarro asked her mother what time she was going to bed, and slipped out of the house when she was asleep.

Nunez suspected Alicia may have been abducted by someone she met online gaming.

‘I’m more than 90 percent sure that my daughter met this person online,’ she claimed at the time.

The mother said her daughter was a pretty cautious person, so it would have been unusual for her to be easily lured.

‘Knowing the way my daughter’s personality is, I don’t think that she would have fallen for that,’ Nunez said. ‘This person probably took a while to be able to gain [her] trust.’

In a Facebook video on Wednesday, Navarro said she feels relief knowing that her daughter is alive and well

Navarro had long suspected that her daughter was abducted by someone she met online gaming, though police were never able to find any proof of that

Over the years, Nunez partnered with various private investigative services, put up billboards, appeared on television programs and used social media in her efforts to find her daughter.

Meanwhile, the Glendale Police Department followed up on thousands of leads regarding Alicia’s disappearance.

It reported last year that it was getting at least one tip a week about Navarro’s disappearance, but there was never any concrete evidence she was abducted.

Now, Nunez said in a Facebook video, she just feels relief.

‘I, first of all, want to give glory to God for answering my prayers and for this miracle,’ she said. ‘For everyone who has missing loved ones, I want you to us this case as an example that miracles do exist and never lose hope, and always fight.’

She said she didn’t yet have all the details about her daughter’s disappearance, ‘but the important thing is that she is alive.

‘I want to thank the community and God for all that you have done,’ she said.
