Two Federal Convictions Listed

The supplied registry record lists two federal convictions for abusive sexual contact.

The second conviction occurred in October 2004.

The supplied registry information says that case involved a 12-year-old female victim.

A historical report confirms Thompson faced a federal abusive sexual contact case in 2004.

The federal case began with an indictment issued in April 2004.

The supplied registry record later lists an abusive sexual contact conviction from that year.

This story does not report a new arrest or a new criminal charge.

It concerns Thompson’s current registration information and the two listed federal convictions.

Federal law addresses abusive sexual contact under Title 18 of the United States Code.

The current law appears under 18 U.S.C. § 2244.

The statute covers several forms of prohibited sexual contact under federal jurisdiction.

Penalties depend on the conduct and circumstances involved in each case.

Federal statutes have also changed since Thompson’s older convictions.

The record supplied to TRF News identifies Thompson as a Tier 3 offender.

South Dakota uses three registration tiers for people required to register.

Current state law requires Tier III registrants to remain registered throughout their lifetime.

Tier II registration lasts at least 25 years.

Tier I registration lasts at least five years.

The South Dakota Division of Criminal Investigation maintains the state’s public sex offender registry.

Registration information can change after address, custody, or verification updates.

Readers should use the South Dakota Sex Offender Registry for current information.

Registry information should not be treated as proof of a new crime.
