I hope something will be done about it but like so many other cold cases, the victim or victims, do not usually see any fruition on their cases. It is very frustrating because the police had enough evidence to arrest the two people but said they didn't have enough evidence to indict them. I don't understand this. Arrest them and let the lawyers argue the case and if there isn't enough evidence to convict, then there isn't enough.
At least make the effort to arrest them and they could have possibly gotten a confession from one of them.
The good thing is that there is no statute of limitations on murder so if some more evidence shows up, they can be arrested.
