The Montana creep linked to then-runaway teenager Alicia Navarro admitted on Monday to hoarding child sex abuse images – and could face decades behind bars, according to prosecutors.

Eddie Davis, 37, pleaded guilty to a count of sexual abuse of children more than a year after it was revealed the pervert was living with Navarro, who went missing from her Glendale, Arizona home in 2019 when she was 14.

Authorities raided the apartment the two shared and found the incriminating evidence shortly after the teen, then 18, walked into the Havre police station in July 2023 and asked to be taken off the missing persons list.

Law enforcement said disturbing content of children under the age of 13, including two images of kids under the age of 5 were on his electronic devices, the Montana Attorney General’s Office said.

The images showed infants and toddlers, and other computer-generated animated content of children being sexualized, the attorney general’s office said.

The crime Davis is pleading to is not connected to Navarro, who is now 20.

It’s unclear how Navarro ended up with Davis, but Davis was identified as Navarro’s boyfriend in charging docs obtained by KTAR last year.

When Navarro answered the door leading up to the search of Davis’ apartment, officers saw the hulking deviant throw his cellphone in the garbage and then put trash on top of the phone to hide it, prosecutors said.

The devices were then reviewed by investigators that led to Davis’ arrest.

After Davis’ home was targeted by police, he and Navarro moved into his parents’ home on a Native American reservation filled with drugs and sex abuse.

He was arrested while Navarro was with him on the way to court in an attempt to change her name, Montana State Attorney General Austin Knudsen previously said.

“It sounds like she was unaware of his activities dealing with child sex abuse material involving children,” he said last year. “It sounds like she did not take that well when she learned of that yesterday.”

Davis’ sentencing is pegged for Dec. 16 in Hill County District Court where the state will request a 100-year sentence with 50 years suspended and a 25-year parole restriction.

Navarro reunited with her family last November to the relief of her mother Jessica Nunez.

“This has been a very difficult journey, but it has a happy ending and today my family is complete,” she said then.

A representative for the family reportedly said last year Navarro and her mother were no longer living in Arizona, and stressed the family had challenges ahead.

Navarro’s disappearance led to a nationwide search, though police noted she “willfully left her home” just days before her 15th birthday.

A missing person report at the time described Navarro as autistic but high-functioning.
