A. T:
Since the Profile manager and the Profile name are the same, it would be best to try sending a private message to him, asking if he plans to do anything with the profile, encouraging him to contibute (volunteer), etc.
Since John's last posting was in 2012 it is quite likely he is alive.
With those things in mind (living person) and the importance of privacy, there is not much else to be done here.
