Jill vanished while on a bike ride eight months ago. They have made headway. Authorities found Jills bike and established a timeline of her bike ride. They are also following other leads, but still don't know what happened. Even though we've interviewed thousands of people, if we need, we'll interview thousands more.
Information is the key.
Searches haven't turned up anything, so investigators are banking on people. Even if the information may seem insignificant, investigators want it. It may give the shot needed to solve the case. Authorities wont talk specifics of the new leads, but are confident this case can be solved. In addition, they would like to talk with a person who may have been driving a black pick-up truck near the area where Jill disappeared.
