For sure. It doesn't have to be one thing of course. There just needs to be connections of some kind between the strands, and more than one way for the players to connect the dots. Based on your characters, you could seed information in police reports, old news articles, you could have additional information available form witnesses who were interviewed at the time (the clues make more sense to the players when they know about the BCV). You could have elderly NPCs from the time, police, news and church. Some of the key players at the time might be dead, but their belongings could be with relatives still in town. Letters, journals, whatever. I prefer to leave the exposition in the hands on NPCs as much as possible, but documents are useful too.
Both the news and the police would have records of all these things. You haven't found a tie-in to the university yet though. Perhaps the uni has an occult department that could be a source of links. Perhaps crazy old professor McGregor was shouting about vampires at the time but no one wanted to believe him. He could be useful source of exposition and is a natural way to connect the now to the then for the players without it seeming forced. If he was 30-odd in the early 60's he'd be in his 60's in 1994- that works.
You're really working two layers. There is the immediate in-the-now events of 1994. Your post seems a little light on that side. What's going on in town now? The now is going to be more important to start than the past as the players need a reason to start digging up info from the 60's. The events in the now need to index that there is a connection to the past, and the past needs to have a lot of handles and hooks in it so that you don't need to nudge the PCs in a particular direction. The PCs should be able to dive into history to connect the dots, but those dots are in the present. That's where you need to link some things up IMO.
