We have no evidence that Wang "was" disappeared. We know that he's nowhere to be found, that the university put him on leave weeks ago [0], and that the FBI recently searched his home. Notably, the university put him on leave weeks before the FBI searched his home.
That sequence is better explained by the hypothesis that Wang vanished himself suddenly and the university called in the FBI to investigate things that they found in the aftermath. (Note that that's still pure speculation, but it's speculation that better accounts for all known facts.)
