A Farmington woman has been charged with criminal sexual penetration involving a minor following an investigation by Farmington police, according to court records.

Emily Paige Lefever, 37, was charged Feb. 18, 2026, in Farmington Magistrate Court with one count of criminal sexual penetration of a child between the ages of 13 and 16, a fourth-degree felony, according to court records.

All charges are allegations based on court records, and the defendant is presumed innocent unless proven guilty in a court of law.

This filing follows a separate Farmington case involving allegations that Lefever provided a vape device to the juvenile referenced in the affidavit. Court records indicate she was previously charged in that case with distribution of tobacco.

Information Learned During Separate Investigation

According to the affidavit sworn by a Farmington police detective, investigators learned during a separate investigation that a male who was 15 at the time allegedly had sexual intercourse in June or July 2024 with an adult female identified in court records as Emily Paige Lefever.

The affidavit states the alleged sexual contact occurred when the male was 15 years old. Court records describe Lefever as 36 years old during the alleged time frame.

According to the affidavit, the information emerged during an investigation in which a counselor recorded a conversation between the juvenile and his mother. In that conversation, the juvenile reportedly described sexual contact with the woman, including statements indicating intercourse allegedly occurred at her residence.

Prior Vape Case Referenced

The affidavit references a September 2024 incident in which officers responded to a report that Lefever allegedly sold the juvenile a vape device for $20. According to court records, she was later charged in that case with distribution of tobacco.

Investigators later obtained a search warrant for the juvenile’s phone and reviewed communications, according to the affidavit. During a January 2026 interview conducted in the presence of legal counsel, the juvenile reportedly confirmed having sexual contact with Lefever and stated the contact allegedly occurred when he was 15 years old.

Interview With Defendant

According to the affidavit, investigators contacted Lefever in late January 2026 and later interviewed her at her residence. Court records state she initially denied having sexual contact with the juvenile.

The affidavit states investigators believed Lefever was being untruthful during questioning.

According to the affidavit, investigators later conducted a polygraph examination during the investigation.

According to the affidavit, Lefever later made statements acknowledging sexual contact occurred at her residence during 2024.

Time Frame of Alleged Conduct

The affidavit states investigators determined the alleged sexual conduct occurred between June 1, 2024, and Sept. 11, 2024. During that period, the juvenile would have been 15 years old, according to court records.

The detective wrote in the affidavit that investigators believed there was probable cause to support the charge based on interviews conducted during the investigation.
