A Harford County man, who was already serving a prison sentence for a state drug dealing conviction, was sentenced this month for a federal heroin distribution conviction in an unrelated case.

U.S. District Judge Ellen L. Hollander sentenced Darryl Malloy Jr., 32, to 12 years in prison, followed by four years of supervised release, for possession with intent to distribute 100 grams or more of heroin, according to the Maryland U.S. Attorney's office. Malloy pleaded guilty to the federal charge in June, according to court records.

During the sentencing in U.S. District Court in Baltimore on Aug. 8, Hollander ordered that Malloy's federal sentence be served concurrent with the 20 year sentence – with all but eight years suspended – that he was already serving on the unrelated state conviction, the U.S. Attorney's Office said in a statement.

In February 2013, Malloy pleaded guilty in Harford County Circuit Court to one count of possession with intent to distribute narcotics, according to Maryland court records.

Malloy, whose address in Maryland Court records is the 3000 block of Goat Hill Road in Abingdon, was arrested in the heroin case while he was free and awaiting sentencing for the Maryland conviction, according to Harford County State's Attorney Joseph Cassilly. He was sentenced in the latter case on Dec. 5, 2013, according to court records.

According to Malloy's plea agreement in the federal case, on Nov. 15, 2013, Malloy purchased more than 100 grams of heroin in Towson, and transported it to a motel in Edgewood, identified in court documents as the Ramada Inn, where Malloy was staying. He admitted he intended to divide the heroin into smaller quantities and package it for distribution, the agreement states.

The plea agreement also states that any assets "directly traceable to his offense..." will be subject to forfeiture and that Malloy agreed to "assist fully in the forfeiture."

In announcing the conclusion of the federal case against Malloy, U.S. Attorney Rod J. Rosenstein praised the Drug Enforcement Administration and the Harford County Narcotics Task Force for their work in the investigation.
