Federal prosecutors say a long-troubled North Baltimore block is at the center of a new federal case, with five men now facing charges after an ATF-led investigation into an alleged drug trafficking organization on the 500 block of Sheridan Avenue. Authorities say the probe involved months of undercover work and targeted searches that came to a head earlier this month with multiple arrests and search warrants.
The defendants are identified as Omar Gilliam, 43; Derrell Washington Coates, 42; Kevin Harris, 34; Darren Farmer, 36; and Stephen Oliver, 38. Prosecutors say Gilliam, Coates, Harris, and Farmer are charged in a federal indictment with conspiracy to distribute and possess with intent to distribute controlled substances, including heroin, fentanyl, and crack cocaine, while Oliver is charged with distribution counts. Gilliam and Oliver also face firearm offenses tied to prior convictions, according to WBAL.
How investigators built the case
Officials say the investigation began in August 2025 and leaned on confidential informants, controlled buys, surveillance and crime-gun intelligence to map out alleged stash locations and sellers. According to the ATF Baltimore Field Division, four suspects were arrested on April 8 as officers served search warrants on the 500 block of Sheridan Avenue and at additional properties in both Baltimore City and Baltimore County.
During those searches, authorities say they recovered several firearms along with nearly 400 grams of suspected narcotics. ATF officials credit the agency’s Crime Gun Intelligence work and partnerships with local law enforcement with helping establish probable cause for the arrests and warrants.
Sheridan Avenue's enforcement history
Federal court filings and past press releases from the U.S. Attorney’s Office show the 500 block of Sheridan Avenue has surfaced repeatedly in drug and firearms investigations in recent years. Prosecutors say that pattern of activity helped drive the latest operation.
Baltimore Police Commissioner Richard Worley, who called the block a historical problem, told reporters the new arrests could “give that community some stabilization and peace,” as reported by WBAL. Earlier federal filings also reference ongoing enforcement on Sheridan Avenue, according to records from the U.S. Attorney’s Office.
What happens next
The U.S. Attorney’s Office has filed the charges and will prosecute the case in federal court. Court officials will schedule initial appearances and any detention hearings, according to an announcement from the U.S. Attorney’s Office.
The defendants are presumed innocent unless and until they are proven guilty in court. Future details on arraignments, motions, and other filings are expected to appear in federal court records and in additional public statements from the U.S. Attorney’s Office.
