Northeast Radio SD News – Watertown, SD - Frederick Frank Grimes, 60, has been sentenced to 10 years in the state penitentiary with six years suspended after pleading guilty to a Class F4 felony drug charge.


According to court records finalized on July 29, 2026, Grimes entered a guilty plea on July 1, 2026, to one count of Manufacture, Distribution, or Possession of Schedule I or II Drugs.


On July 29, 2026, the court handed down a 10-year penitentiary sentence for the felony conviction, suspending six years of the term. Grimes was granted 63 days of credit for time already served, with the incarceration period formally beginning July 29.


In addition to his prison sentence, Grimes was ordered to pay financial penalties and specific state reimbursements:

·         Fines and Fees: A $500.00 fine, $50.00 in court costs, and $66.50 in surcharges.

The initial indictment included multiple counts of Schedule I or II drug distribution and possession, keeping a place for the use or sale of controlled substances, and possession of drug paraphernalia.
