KNOXVILLE (WATE) - A grieving Knoxville mother is taking action in hopes of putting her son's killers behind bars.
Elizajuan Stuart, 17, was shot to death in August 2010. He was found in an alley behind Magnolia Avenue right after football practice .
His mother, Taloni Stuart Lee, protesting Friday outside the Knoxville Police Department, holding signs and wearing crime tape over her mouth.
Lee says she believes the city of Knoxville has too many unsolved homicide cases, and too many of them are in East Knoxville.
"We got to step it up," said Lee. "I'm not saying there's not good cops or investigators. There's great investigators I've run into, some great cops, but they got to step up their game."
Her son was an Austin-East High School football star.
Lee believes police know who killed her son. One man was arrested shortly afterward, but Lee says he was released. She also believes two other people were involved.
"Even though they have suspects, the suspects continue to walk the street."
Lee says she will return to the police department every morning until she gets justice for her son.
She explained the symbolism of the crime tape she wore over her mouth during the protest. "I put it on my mouth because everybody is silent about it until it happens to them or they're silent because they don't think anything is going to change. But you can't expect change if you don't do something different."
Lee hopes the community will get involved and join her in protest.
When asked for comment about the Elizajuan Stuart case, Knoxville police officials only said it's still under investigation.
