Rapid City Man Convicted of Sexual Abuse and Child Abuse Committed on the Pine Ridge Reservation

RAPID CITY - United States Attorney Alison J. Ramsdell announced that a jury has convicted Victor Dominquez, age 57, of Rapid City, South Dakota, of one count of Aggravated Sexual Abuse of a Minor, five counts of Abusive Sexual Contact, and two counts of Felony Child Abuse following a three-day jury trial in federal district court in Rapid City, South Dakota. The verdict was returned on February 5, 2025.

The defendant faces a mandatory minimum penalty of 30 years up to life in custody. Each conviction carries the possible maximum of a $250,000 fine, a term of supervised release of up to life, and a $100 special assessment to the Federal Crime Victims Fund. Dominquez was indicted by a federal grand jury in June 2024 for the listed charges. 

Evidence at trial established Dominquez sexually abused his biological daughter and stepdaughter for years while the family lived on the Pine Ridge Reservation between 2006 and 2012.  Dominquez used a variety of tactics against the children to prevent them from disclosing the sexual abuse. He created an environment of fear by beating the children in the home, resulting in a charge of child abuse. He also groomed the girls by showing them pornography beginning when they were very young. The sexual abuse and domestic violence persisted throughout the girls’ childhoods, and they ultimately disclosed the abuse when they were adults. 

This case was investigated by the FBI. Assistant U.S. Attorney Anna Lindrooth prosecuted the case.

A presentence investigation was ordered, and sentencing has been scheduled for April 14, 2025. Dominquez was remanded to the custody of the U.S. Marshals Service.
