The indictment, issued in August, also charges the men with aggravating circumstances — which could carry an additional penalty if they are convicted of murder.
The indictment charges that on Dec. 17, 2011, Proctor, Williams and Jackson, along with another co-conspirator, robbed, assaulted and killed Blackwell at the 900 block of Burns Street SE.
Blackwell had previously assaulted and robbed Proctor and Williams and the attack on Blackwell was in retaliation for that crime, the indictment alleges.
According to the indictment, the co-conspirator convinced Blackwell to leave his home to meet them somewhere, but the group waited outside for him.
Williams and Jackson then chased Blackwell on foot, armed with a knife and brass knuckles, while Proctor followed in a vehicle, according to the indictment.
When they caught up to Blackwell, they stole his coat and cell phone, before stabbing him several times. Blackwell died in January.
Witnesses told the grand jury that Proctor, Williams and Jackson were intoxicated at the time of the crime and continued to drink afterward. Officers found Blackwell at about 10:30 p.m., according to charging documents.
Witnesses who testified before the grand jury said that moments after the assault, Proctor, Williams and Jackson were intoxicated more than they had ever been before. Prosecutors used emails, text messages, and Facebook posts to build the case.
