"Why can't they bring these people to justice?" she asked.
No one has come to trial in the November 19, 2005 crime that shocked the Triangle. Washington's son Jamal Halloway, 27, was killed - along with Lajuan Coleman, 27, Jonathan Skinner, 26, and Lennis Harris Jr., 24.
In 2005, police said the four men were the targets of a drug-related robbery. Officers responding to the slayings found the four dead men lying on the carpet of a small second-story bedroom, each shot in the head. Investigators said forensic tests showed a 9mm handgun found at the scene was used. Two other men in the townhouse in the Breckenridge subdivision off Hope Valley Road were found wounded.
Almost a year after the killings, a man already in custody on federal drug trafficking charges was indicted. Rodrick Vernard Duncan, now 33, was charged with four counts of first-degree murder.
But Duncan has never come to trial. He's serving a 10-year-sentence in federal prison on drug charges. According to court records, he won't be released from federal prison until January 2015.
The Durham district attorney's office told ABC11 that he has never been to court on the murder charges because his federal sentence has become an obstacle.
Family members told ABC11 Tuesday that police investigators told them they believed there were multiple suspects involved, but no other arrests have been made.
Durham police declined ABC11's request for an interview.
