Two Wilmington Men Charged with Federal Fentanyl and Gun Offenses

WILMINGTON, Del. - Two Wilmington men were arrested March 10, 2026, for unlawfully possessing guns and over 400 grams of fentanyl.

According to court documents, Marcus Warren and Donavan McGriff, both 35, were the subjects of a drug investigation conducted by the Drug Enforcement Administration (DEA) and the New Castle County Police Department (NCCPD).

On Tuesday, March 10, 2026, members of the DEA, NCCPD, and the Delaware State Police Special Operations Response Team executed search warrants for Warren and McGriff, their residences in Wilmington, and McGriff's car. Both Warren and McGriff were occupants of the car at the time of the search. The car search revealed over 400 grams of fentanyl pills.

The search of Warren's residence resulted in the recovery of approximately one kilogram of suspected fentanyl and three guns, including a privately made firearm or "ghost gun" with no serial number. The search of McGriff's residence resulted in the recovery of an additional gun.

Warren is charged with possession with intent to distribute more than 400 grams of fentanyl and possession of a firearm by a prohibited person. If convicted, Warren faces a mandatory minimum penalty of 10 years in prison and a maximum penalty of life in prison.

McGriff is charged with possession of a firearm by a prohibited person. If convicted, McGriff faces a maximum penalty of 15 years in prison.
