LEONARDTOWN, Md. – Following an extensive undercover investigation, two suspects were arrested and charged with multiple drug trafficking and firearm-related offenses on Thursday, December 5, 2024. Antwian Marquis Johnson, 38, and Shannon Marie Johnson, 37, both of Great Mills, were apprehended during the execution of two search and seizure warrants on separate residences in Great Mills and Hollywood. Pursuant to the search warrants, detectives seized approximately 21.5 kilograms (47 pounds) of suspected cocaine, crack cocaine, and fentanyl with an approximate street value of $2,160,600.
Early Thursday morning, detectives from the Criminal Investigations Division executed a search and seizure warrant at a residence in the 45000 block of Daugherty Court in Great Mills. During the search, deputies recovered over $75,000 in U.S. currency and two firearms. A subsequent search of a second residence in the 24000 block of Old Hollywood Road in Hollywood uncovered significant quantities of controlled dangerous substances (CDS), including more than 200 individually packaged bags of CDS, indicative of high-volume, street-level distribution and bulk quantities of CDS, indicative of high-level narcotics trafficking. Investigators also seized CDS paraphernalia and four vehicles.

Antwian Marquis Johnson faces 12 charges, including two counts each of CDS possession – large amount, CDS possession with intent to distribute, possession of a firearm in relation to a drug trafficking crime, CDS possession – not cannabis, and CDS – proceeds from offense, and one count each of CDS – production equipment and possession of a firearm after being convicted of a disqualifying crime.
Shannon Marie Johnson is charged with nine offenses, including two counts each of CDS possession – large amount, CDS – proceeds from offense, conspiracy to possess CDS with intent to distribute, and CDS possession – not cannabis, and one count of CDS – common nuisance for keeping a vehicle for the purpose of illegally administering CDS.
Both are incarcerated at the Detention and Rehabilitation Center in Leonardtown.
Following the arrests, Sheriff Steve Hall said, “Thursday’s operation was the largest narcotics seizure in St. Mary’s County Sheriff’s Office’s history, as well as one of the most significant seizures in the Southern Maryland region. I witnessed the profound sense of accomplishment by the deputies involved in the operation, which is only surpassed by my pride in them. It is a privilege to lead these guardians who tirelessly fight against those intent on poisoning our community.”
