(KLZA)-- A Rock Port, Missouri man faces 20 years to life in federal prison after he plead guilty in federal court Monday to selling fentanyl to another Atchison County, Missouri man that resulted in his fatal overdose.

23-year-old Quentin W. Carder entered the plea before U.S. District Judge Howard F. Sachs to one count of conspiracy to distribute fentanyl and cocaine, which caused the death of another person, and one count of distributing fentanyl which caused the death of another person.

Carder admitted to distributing four blue pills that appeared to be oxycodone, butn which were counterfeit and actually contained fentanyl, to a person identified as “C.L.” on June 18, 2021. Carder had previously supplied this person with cocaine.

In the early hours of June 20, 2021, C.L. Used one of the fentanyl pills obtained from Carder, and later that morning, C.L.'s father found him unresponsive in his bedroom in medical distress. C.L. Was transported to a hospital for medical attention but eventually died on June, 22, 2021.

A forensic toxicologist concluded the victim would not have died but for acute intoxication of fentanyl.

Carder is subject to a mandatory minimum sentence of 20 years in federal prison without parole, up to a sentence of life in federal prison without parole.

A sentencing hearing will be held after completion of a presentence investigation by the United States Probation Office.

U.S. Attorney Byron Black is prosecuting the case, which was investigated by the Drug Enforcement Administration, Missouri Highway Patrol and the Atchison County, Missouri, Sheriff's Department.
