A D.C. man was found guilty Tuesday of an incident that prosecutors described as an “attempted execution” of three men during a drug robbery.

Herbert Arrington, 26, of the District, was found guilty of multiple charges, including assault with intent to kill, aggravated assault while armed, assault with a dangerous weapon and possession of a firearm during a crime of violence. He is scheduled for sentencing in D.C. Superior Court on June 7.

According to prosecutors, the charges stemmed from an incident on June 9, 2010, when Arrington arranged to purchase a large amount of marijuana. That evening, he met three men inside a parked GMC Yukon in the 2100 block of 8th Street NW. After one of the men handed over the marijuana, Arrington pulled out a gun and shot all three men at point-blank range, prosecutors said.

All of the victims suffered gunshot wounds, and two were seriously injured. D.C. police officers, who were working off duty at a nearby nightclub, heard the shots and responded, prosecutors said.

All three victims survived the attack. Arrington, who had fled with the marijuana, was arrested six days later.
