Police say Williams was not the intended target.
Williams was a junior at Robeson High School, a former member of the Jesse White Tumblers and had dreamed of going to college on an athletic scholarship.
Williams' parents went into the neighborhood Wednesday where Fenton was last seen to try and bring the suspect to authorities.
There was no fear as Willie Williams, Jr. dodged traffic. He has already had the worst thing happen to him; his son preceded him in death. Now, he wants to find his son's killer showing passing strangers the suspect's photo.
In 2006, Willie Williams III was leaving a movie at the Ford City Mall. A fight broke out and as Williams went to pull his friend out of the brawl he was shot in the head.
The case went cold until a few months ago. People came forward with information. Now, the Williams family and authorities hope the community will help locate the suspect."If you know where Eddie is, call someone and let us know. It's safer for him. It's safer for us," said Supt. Jody Weis, Chicago Police Department.
"We just need to know where he is because a man who has a record and a man who is wanted for murder is a dangerous man," said Father Michael Pfleger, St. Sabina Catholic Church.
St. Sabina Church, where Williams parents are members, is offering a $5,000 reward. At the church Wednesday, the Williams family stood with other families affected by gun violence, the police superintendent and Fr. Michael Pfleger to plea for help in finding the suspect.
"I can sit up here and talk about him all day. I miss my son, my family, we miss Willie. A lot of sleepless nights. Just need your help to turn him in," said Willie Williams Jr., victim's father.
"My son was a good kid. And only the Lord knows why this could have happened to him. And I'm asking all mothers, brothers, sisters, friends. Someone knows. Please give us closure," said Indira Rutues, victim's mother.
Fenton is known to frequent the Marquette Park neighborhood where friends and relatives of Willie Williams focused their attention Wednesday.
Fenton's mother urged him Thursday night to contact her so she can help him surrender to police.
"If you don't do it with me, and they get you, it's going to turn out wrong, and I don't want to see that happen. I love you," said Lorna Williams, Fenton's mother.
If you have information about Fenton's whereabouts, call police. He is considered armed and dangerous.
