ROSEBUD, S.D. - A 22-year-old Mission, South Dakota man has been sentenced to 25 years in prison for kidnapping and sexually abusing a juvenile girl. Canku Martinez was found guilty of Aggravated Sexual Abuse and Kidnapping during a four-day jury trial.

“Mr. Martinez engaged in a despicable course of conduct in this case and subjected the victim to unthinkable sexual violence.  The sentence he received today reflects the seriousness of his crimes,” said U.S. Attorney Alison J. Ramsdell.

In the early morning hours of Oct. 29, 2023, Martinez agreed to drive the juvenile home from a party near Rosebud. However, instead of giving her a ride home, he took her to a secluded area outside of Rosebud and made sexual advances. When the girl rejected his advances, Martinez displayed a knife and forced her to engage in sexual activity.

When Martinez dropped the victim off at her house, he told her not to tell anyone what had happened. Martinez then left the local area shortly after. The FBI and Rosebud Sioux Tribe Law Enforcement Services investigated the case.

“Bringing this defendant to justice is the result of tremendous cooperation between federal and tribal law enforcement,” said Ramsdell.
