Who killed her brother, Jovan Willis, who was just 14-years-old at the time?
He was gunned down on the city's west side in 1991. He was walking with a friend when someone demanded his jacket, but as the teen started to run away he was shot.
"We're here today pleading for help to solve my brother's murder. Not only for my family's closure, but because his loss potential represents the potential we lose every single day in our community when we're losing "Jovans", when we're losing future doctors," Jenkins said at a Crime Stoppers news conference Thursday.
"It has been hard on family. The pain doesn't go away," says Jovan's mother, Jo Jenkins.
But the teen's family is not giving up hope.
Crime Stoppers is offering a cash reward up to $2,500 for information leading to an arrest.
You're asked to call 1-800-SPEAK-UP if you have that information. You will remain anonymous.
