Although two individuals are serving a life sentence in connection with this murder, we have always known there were other people involved in the attack ...

We believe there were people in the area that night who may have seen something. Not the murder itself necessarily but events or individuals leading up to the event.
I am taking this opportunity to appeal directly to those people to come forward and speak to us. You may think you won't remember something from so long ago, but we would still implore you to come forward.
