Williams was sentenced July 26 in a cramped courtroom by Reed. There were only two benches for members of the public.

That meant families of the victim and the suspect had to scrunch together in the few seats available.

A skirmish had broken out during a different hearing earlier that day, and the relatives of Poindexter and Williams were warned to keep their emotions in check.

The Poindexters delivered their victim impact statements. Barbara Poindexter was first.

"I didn't know I could hurt this bad," she told Reed. "I didn't know I could drive around the city and get lost in a place I've lived my whole life."

She then turned her gaze to Williams. Separated by less than 10 feet, two attorneys and some rickety wooden chairs, she told him that he had betrayed young Quintin.

"You may have been in the same gang, but Quintin loved you. He looked up to you. He respected you," she told him. Williams, with his thick beard and bald head, stared right back.

"If you never know another person who loves you, know that Quintin did," she said.

Gerard got up and unleashed a quiet fury.

"I will always have the hatred I have, and it will never go away, diminish or die," he said calmly. Perhaps some day it will subside, he said. "But today I hate."

When it was his time to speak, Williams said that he did not shoot "Dexter" or know that it was going to happen.

He said he took the plea deal only because his "back was up against the wall" and he would have faced more prison time had he not accepted.

On Tuesday, he tried to revoke the plea, but a judge denied the request.

As for Quintin's immersion into gang life, Williams said he "didn't have anything to do with that, but I let him become a part of it."

"He made the decision himself, as a man," Williams said.

Since Quintin's death, Barbara and Robin Poindexter have been visiting schools, showing his picture and speaking about the insidious nature of gang violence.

They talk about decision-making, and urge kids to stay with their "original gang — your family."
