I have seen Allan’s dads Facebook page & you are right their dedication to find Alan has never wained....they even drive around in a “Find Allan” van, forever trying to appeal to the conscious of locals. Allan’s dad believes he knows who the killer is and that there were others there that night who also know but it seems no witnesses are prepared to come forward. Time changes everything and relationships also change, hopefully one day one of those witnesses priorities will change & they will go to the police with what they know. I don’t think they will ever give up until they have Justice for their son. Allan will be looking down on all they are doing to find him & will know how much he is loved.
