Testimony from 26 years ago will be enough of a problem for the prosecutors to overcome.
It sounds as if you have no particular knowledge about the actual crime, though. You can only testify to what you have seen and since you apparently saw very little there is not much you can testify about. A fair question to put to the investigators would be "what is it exactly that you think I can help you with?" They may not even know themselves at this point. They are simply looking for anyone who might provide background.
