Conspirators Caught Through Sting Conducted by ATF’s Violent Crimes Task Force

ALEXANDRIA, Va. — Six men from Philadelphia were convicted today of conspiring to conduct an armed home invasion robbery of a drug stash house in Fairfax County.

Neil H. MacBride, United States Attorney for the Eastern District of Virginia; Rich Marianos, Acting Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms and Explosives’ (ATF) Washington Field Division; Colonel David Rohrer, Fairfax County Chief of Police, and Stan Barry, Fairfax County Sheriff, made the announcement after the verdict was accepted by United States District Judge Liam O’Grady.

Indicted on Dec. 28, 2010, Senh Phun, 31; Khem Un, 27; Saraeun Min, 25; Marc Eric Johnson, 26; Jan Stevens, 29, and James McCallister, 27, all of Philadelphia, Pa., were convicted today of conspiracy to commit robbery and possession of firearms in furtherance of the robbery conspiracy. Phun, Un, Min, and Johnson were also convicted of conspiring to possess with intent to distribute five kilograms or more of cocaine. McCallister and Stevens were acquitted on the drug charge.

The defendants will be sentenced on June 17, 2011. Un and Johnson face a mandatory life sentence. Phun and Min face a mandatory minimum sentence of 15 years in prison and a maximum life sentence. Stevens and McCallister face a mandatory minimum sentence of five years and a maximum 25 years in prison.

According to court records and evidence at trial, in June 2010, a confidential informant advised law enforcement that Phun was interested in conducting a home invasion robbery. Undercover detectives provided Phun with the opportunity to rob a drug stash location in Fairfax County, Va. On Oct. 28, 2010, Phun’s associates – Un, Min, Johnson, Stevens and McCallister – arrived in Fairfax County armed with five handguns, latex gloves, and restraints to commit the robbery. After undercover detectives confirmed each man’s intention to commit the robbery, all five men were arrested. Phun was arrested in Philadelphia on the same day.

This case was investigated by the ATF Violent Crimes Task Force, which includes personnel from the Fairfax County Police Department and Fairfax County Sheriff’s Office. Assistant United States Attorney Mary K. Daly and Special Assistant United States Attorney Marc J. Birnbaum are prosecuting the case on behalf of the United States.
