SIOUX FALLS - United States Attorney Alison J. Ramsdell announced today that U.S. District Judge Charles B. Kornmann has sentenced a Sisseton, South Dakota, man convicted of Sexual Abuse of a Minor. The sentencing took place on November 5, 2024, in Aberdeen, South Dakota.

Daniel Oscar Seaboy, age 23, was sentenced to eight years in federal prison, followed by five years of supervised release. He was ordered to pay a $200 as a statutorily required special assessment to the Federal Crime Victims Fund.

Seaboy was indicted by a federal grand jury in April of 2024. He pleaded guilty on August 19, 2024.

In March of 2023, a 13-year-old female and a 14-year-old female were at Seaboy's house visiting another minor female. Seaboy provided alcohol and marijuana to the girls. Seaboy then had sexual intercourse with the 14-year-old female and infected her with a sexually transmitted disease. Seaboy also had sexual intercourse with the 13-year-old female without her consent.
