A 22-year-old Lawrence man is facing charges of unlawful possession of a firearm and ammunition and possession of cocaine and marijuana with intent to distribute. Jabed Nguyen of Union Street was followed to his apartment by police officers and special agents after he was noticed acting suspiciously in the building’s hallway. Law enforcement personnel were there to apprehend a different man, who turned out not to be there, when they saw Nguyen allegedly attempt to avoid them. Nguyen is the son of Thu Nguyen, a 59-year-old Chinese food delivery man who was killed in July 2009 when he tried to bring a food order to the Stadium Housing project. Two men were charged with that murder. Jabed Nguyen is the youngest of his three children.
