Two people were arrested at a Kuna home Wednesday and booked into the Ada County Jail, each facing a felony charge of aggravated lewd conduct with a minor child 12 or under. Guillermo Madrigal Marin, 26, and Brieana Madrigal Marin, 24, were taken into custody at the residence following an investigation prompted by law enforcement concerns.
Kuna Police detectives arrested the pair on Wednesday, according to KBOI, which reported that the charges stemmed from an investigation following law enforcement concerns. The Ada County Sheriff's Office is withholding additional information about the case, citing the nature of the charges and the victim's relationship to the suspects, the station reported.
Kuna Police operate under a long-standing contract with the Ada County Sheriff's Office, a municipal service agreement dating back to 1998 that gives the smaller city access to the county's detective divisions and specialized investigative units, according to the City of Kuna. Kuna Police led the investigation into the Madrigal Marin household.
What the Charges Carry Under Idaho Law
Both defendants were booked on charges of felony aggravated lewd conduct with a minor child 12 or under. Idaho Code § 18-1508 defines felony lewd conduct with a minor as committing any lewd or lascivious act upon or with a child with intent to gratify or appeal to sexual desires, per the Idaho State Legislature. A conviction under that statute carries a maximum penalty of life imprisonment in the state prison system.
The reported charge involving a child 12 or under falls under Idaho Code § 18-1508C. The aggravated version of the charge outlined in Idaho Code § 18-1508B applies to offenses involving a minor under 16 but at least 13 and sets a mandatory minimum fixed prison term of 25 years if any two listed aggravating factors occurred, according to Justia Law.
Case Context
Child abuse and sex crime investigations in Ada County typically involve coordinated efforts between law enforcement, the Idaho Department of Health and Welfare Child Protection Services, and special victims prosecutors, reflecting the multi-agency infrastructure built around cases involving young victims. In adjacent Treasure Valley jurisdictions, felony child sex crime convictions have frequently resulted in multi-decade fixed prison terms alongside 50-year no-contact orders protecting minor victims, according to the Canyon County Prosecutor's office, offering a regional benchmark for how similar cases have concluded.
No additional details about the investigation or the identity of the victim have been released. The Ada County Sheriff's Office has not said when the Madrigal Marins are expected to appear in court.
