Overdose Death of Johnson County Teen Launched Federal Investigation

KANSAS CITY, Mo. - An Independence, Mo., man was indicted by a federal grand jury today for his role in a conspiracy to distribute fentanyl and illegally possessing firearms.

Demarkus Q. Shelton, 44, was charged in a 16-count indictment returned by a federal grand jury in Kansas City, Mo. Today's indictment replaces a federal criminal complaint that was filed against Shelton on Aug. 2, 2024, and includes additional charges.

According to an affidavit filed in support of the original criminal complaint, the investigation began on Feb. 22, 2024, when a teenager was found dead of an apparent overdose in Johnson County, Mo. Evidence at the scene, including fentanyl and smoking paraphernalia, indicated the victim had been using fentanyl prior to his death. An autopsy was conducted, which cited a cause of death as the toxic effects of fentanyl.

Investigators learned the overdose victim was among several Johnson County youth who allegedly purchased fentanyl from Shelton earlier that same day.

The affidavit cites a series of controlled purchases from Shelton resulting in the seizure of over 95 grams of powder or "raw" fentanyl. As little as two milligrams of fentanyl can be fatal. During the drug transactions, the affidavit says, Shelton was usually armed with a handgun with a drum magazine and/or an AK-47 or AR-style rifle. In one transaction, Shelton allegedly sold the confidential informant a Palmetto State Armory AR model multi-caliber firearm with a 30-round magazine in addition to 22.7 grams of powder fentanyl for $2,300.

On Aug. 5, 2024, law enforcement officers executed a search warrant at the hotel room where Shelton was arrested on the complaint. Officers found a Taurus .40-caliber semi-automatic firearm and a Taurus .22-caliber semi-automatic handgun.

Under federal law, it is illegal for anyone who has been convicted of a felony to be in possession of any firearm or ammunition. Shelton, who is on state probation, has prior felony convictions for possession of a controlled substance, burglary, and tampering with a motor vehicle.

The federal indictment charges Shelton with one count of conspiracy to distribute fentanyl, seven counts of distributing fentanyl, six counts of possessing a firearm in furtherance of a drug-trafficking crime, and two counts of being a felon in possession of a firearm.

This case is being prosecuted by Assistant U.S. Attorney Ashleigh A. Ragner. It was investigated by the Jackson County Drug Task Force and the Missouri State Highway Patrol.
