Farmington woman accused of having sex with teen

New Mexico’s legal age of consent is 16.

Emily Paige Lefever, 37, was arrested and charged with a single count of fourth‑degree felony criminal sexual penetration of a child. She had a relationship with the boy from from June 1 to Sept. 11, 2024, the affidavit says.

Farmington police began investigating the case Dec. 30, 2025, when the victim’s sister disclosed the information to a counselor, who shared it with the boy’s mother.

The boy then reportedly told his mother he had sexual relations with Lefever at her house in south Farmington, according to the affidavit.

When detectives interviewed the teen, he said Lefever allegedly “had been buying him THC pens and nicotine vapes for approximately six to eight months,” until his mother found out and reported it in September 2024, the affidavit says.

Lefever was charged at that time with distribution of tobacco, according to the affidavit.

About a month before that charge, the boy told police that he and a friend “made a bet to see who could have sex with Emily first,” the affidavit says.

The boy reportedly approached her, told her he had never had sex and asked “if she could ‘help him out,’” according to the affidavit.

A few days later, he reportedly went to her home and allegedly engaged in sexual relations with Lefever until she told him she needed to pick up her children from school, the affidavit says.

The boy also told police that he told Lefever more than once that he was “only 15,” the affidavit says.

Investigators interviewed Lefever on Jan. 30. She admitted knowing the boy and said he was friends with her 15‑year‑old daughter but denied having sexual relations with him, the affidavit says.

Lefever submitted to a Feb. 12 polygraph test at the Farmington Police Department. Investigators asked her if she had sex with the boy and if she engaged in “sexual contact” with him, the affidavit says.

Lefever “responded by answering ‘no’ to all relevant questions, and maintained her innocence,” until investigators told her the “results clearly indicated deception,” the affidavit says.

She then “began to cry,” and reportedly admitted the 15‑year‑old “asked her to have sex,” and that “previous sexual trauma” led her to agree, according to the affidavit.

Lefever told investigators the act lasted only 30 seconds and she stopped because “the whole situation ‘felt awkward, and not natural,’” the affidavit says.

She was booked into the San Juan County Detention Center on Feb. 18 and was released the next day to Pretrial Services supervision, court records state.

A no‑contact order was issued Feb. 19 by Magistrate Judge Stanley King, who told Lefever to stay away from the alleged victim.

She is scheduled to return to Farmington Magistrate Court at 8:30 a.m. March 11 for a preliminary examination.
