Texas Man Sentenced for Failure to Register as a Sex Offender

For Immediate Release
U.S. Attorney's Office, District of South Dakota

United States Attorney Randolph J. Seiler announced that a McAllen, Texas, man convicted of Failure to Register as a Sex Offender was sentenced on November 14, 2016, by U.S. District Judge Roberto A. Lange.

Dimas DeLeon, a/k/a Leo Castro, age 30, was sentenced to 23 months in custody, followed by 5 years of supervised release, and a $100 special assessment to the Federal Crime Victims Fund.

DeLeon was indicted by a federal grand jury on July 19, 2016.  He pled guilty on August 29, 2016.

The conviction stemmed from an incident wherein DeLeon failed to register as a sex offender from May 1, 2016, to July 1, 2016.  DeLeon had initially been convicted in federal court in Texas in 2009 of Sexual Assault of a Child and was sentenced to prison, as well as being required to register as a sex offender. 

In May 2016, DeLeon moved from Texas to Pierre, South Dakota, where he resided with his brother and then girlfriend.  According to the SD Division of Criminal Investigation Sex Offender Registry, DeLeon never registered either his address or his employment in the state of South Dakota.  He also never notified the state of Texas that he was relocating to South Dakota.

The investigation was conducted by the U.S. Marshals Service. Assistant U.S. Attorney Meghan N. Dilges prosecuted the case. 

DeLeon was immediately turned over to the custody of the U.S. Marshals Service.
