Hollis was killed when someone in a passing car fired on the car she was in with relatives.

The family voiced their frustrations that the crime remains unsolved.

"To bring peace into Jacksonville and show others around the world that there are people that really care and that Tiphne is going to make a difference," Hollis' grandmother, Elouise Whitaker, said. "Her death is not in vain."
