John Larvie, Failure to Register as a Sex Offender, South Dakota 2025

Piercing the facade of a seemingly peaceful community in Rosebud, South Dakota, is the disturbing reality of a convicted sex offender who failed to register as required by law.

John Larvie, a 35-year-old man, was sentenced to 10 months in federal prison for his egregious offense. On November 12, 2025, U.S. District Judge Eric C. Schulte handed down the sentence, which also included five years of supervised release and a $100 special assessment to the Federal Crime Victims Fund.

Larvie’s failure to register as a sex offender is a serious matter, given his previous conviction for Aggravated Sexual Abuse in Rosebud Sioux Tribal Court in 2019. As a registered sex offender, he is required to update his registration within three business days of relocation or changing employment or student status.

However, Larvie did not update his sex offender registration until June 4, 2025, after he began a period of supervised release residing in Rosebud on May 6, 2025. This blatant disregard for the law has led to his current predicament.

The case against Larvie was brought as part of Project Safe Childhood, a nationwide initiative launched in May 2006 to combat the growing epidemic of child sexual exploitation and abuse. The U.S. Marshals Service and the Rosebud Sioux Tribe Law Enforcement Services investigated the case, with Supervisory Assistant U.S. Attorney Kirk Albertson prosecuting on behalf of the government.

Larvie’s immediate remand to the custody of the U.S. Marshals Service underscores the seriousness with which the authorities view his offense. As the community breathes a sigh of relief, it serves as a stark reminder of the importance of sex offender registration and the consequences of failing to comply.

The people of Rosebud, South Dakota, can rest a little easier knowing that justice has been served in this case. But as we continue to grapple with the complexities of sex offender registration, it is essential to remember that this is just one small victory in the ongoing battle against sexual exploitation and abuse.
