There's now a $15,000 reward for any information leading to a conviction in the case.
Family and friends, came out Saturday to not only call for justice but send a clear message that this case is far from closed.
"Y'all don't know what y'all did to our family! We hurt every day," said Teague's aunt, Annette Newell. "He meant a lot to us, and y'all took him away from us! Shame on you!"
Teague's loved ones gathered near Roosevelt Road and Racine Avenue to unveil a digital billboard at a West Side bus stop with information on how you could help out in the case.
The 29-year-old was walking home one night last October when police said he was shot multiple times.
Investigators said his body was found lying between two cars on West 14th Street.
He died the next day at the hospital.
"He wasn't just my son, he was my best friend," said Teague' father, Michael Teague.
"Sometimes it's hard to focus, and I just keep pushing. I try to keep pushing because I'm trying to get justice for my son," added Teague's mother, Eyvette Dobbs.
His mother said he was a decorated Army veteran and said she believes someone knows something.
"You don't have to give your name. Just please, information. Any little information can help. He did not deserve this, and I know that people knew my son - know the type of person he was. And, if you have any type of information - please, if you have a heart, just help us because he did not deserve this," Dobbs said. "And, it can happen to your son, your daughter, your mother, your father. You don't want that to happen, and feel the pain that I'm feeling."
Chicago police did release photos of the vehicle and person wanted in connection to this murder.
They said the vehicle is similar to a black GMC Yukon and came directly from nearby Chicago Housing Authority homes and returned there after the shooting.
"I pray the day y'all get caught because he didn't do nothing to y'all," Newell said.
"We need you to get involved. We need you to step up. We need you to turn around and give us that information," added George McDade, chairman of the Cook County Crimestoppers.
If you have any information, you're asked to call police.
