ST. LOUIS – United States District Court Judge Henry E. Autrey accepted a plea of guilty from Keith A. Kos, Jr., on October 12, 2021, for the crimes of distribution of fentanyl and methamphetamine, possession with intent to distribute fentanyl and knowingly possessing a firearm in furtherance of a drug trafficking crime.  Judge Autrey set sentencing for January 18, 2022.

 

According to the plea agreement, the case began on January 6, 2020, when the St. Charles County Police Department were dispatched to an area residence for an overdose death.  A subsequent examination and toxicology analysis revealed the victim’s cause of death was the result of fentanyl and methamphetamine intoxication. 

 

The investigation led to the identification of Kos.  The investigators obtained a state search warrant for Kos’s residence.  Investigators executed the search warrant and seized items including a pistol, more than 400 capsules of fentanyl and other drug paraphernalia.  A subsequent lab analysis revealed the capsules contained 40 grams or more of fentanyl. 


 

Pursuant to the plea agreement, Kos acknowledged and admitted that he knowingly distributed fentanyl and methamphetamine, knowingly possessed with the intent to distribute fentanyl and possessed a firearm while doing so. 

 

The case was investigated by the St. Charles County Police Department and the Drug Enforcement Administration.
