He still is unwilling to respond on his allegations even after I had neutral parties attempt to ask him about it.

What does that say to you? The man destroys an account, won't explain why to anyone.

Pretty sure that means he's:

a) Lying about it
b) Realizes he'd sound like a fool trying to explain it
c) Does not want to admit wrong-doing

Pretty crappy of him and he won't fix it.
