Two Men Admit Role in St. Louis Drug Conspiracy

ST. LOUIS - Two men caught with pounds of fentanyl and other drugs have pleaded guilty to a drug conspiracy charge.

Dennis M. Davis, 47, pleaded guilty Thursday to one count of conspiracy to distribute controlled substances, including fentanyl. Shem J. Guy, 34, pleaded guilty to a conspiracy charge in June. Both men admitted participating in a conspiracy to sell drugs that began at least as early as 2019.

During the investigation, Drug Enforcement Administration special agents caught David, Guy and their conspirators discussing drug purchases and sales. On Sept. 6, 2023, investigators conducted a court-approved search of a Davis "stash" house in St. Louis and found $12,323 in cash, four rifles, two pistols and a money counter. They also found 4.9 kilograms of fentanyl, almost a pound of marijuana, 285 grams of heroin, 168 grams of cocaine, 127 grams of cocaine base and 137 grams of meth. In Davis' house, they recovered three pistols and fentanyl.

Davis is scheduled to be sentenced on Jan. 15, 2026, and Guy on October 1. Davis faces a potential penalty of 10 years to life in prison and a fine of up to $5 million. Guy faces a penalty of up to 20 years in prison, a fine of up to $1 million or both prison and a fine.

Both men have also agreed to forfeit cash, firearms and a 2020 Ram 1500 Big Horn truck that were seized during the investigation.

The Drug Enforcement Administration, the Internal Revenue Service, the FBI, the St. Louis County Police Department, the Bridgeton Police Department, the St. Louis Metropolitan Police Department, and the St. Charles County Police Department investigated the case. Assistant U.S. Attorney James Delworth is prosecuting the case.
