Delete user and posts and search results

[snopes]

Hello,

I wanted to delete a user and I have deleted it.
After this, I wanted to delete his posts and threads and I have deleted it.
After this, i change his name to ****** in all posts where other users tells about him.

After this I run all maintenance systems included rebuild search index but now, when I search by his nick, some results appears but really there arent any reference to this user in our forum.

how can I delete this?
Thanks a lot.

If you search as a regular user does anything still come up?

[snopes]

Yes, forum shows 97 results
As a regular user it shows 89.

But forum shows this ****** where his name is with censored tools.

I would like to remove all about this user...
Thanks a lot

I edit: This is cause there are some threads of this user in a private forum for admins.

Please I need to delete all of this user

Thanks a lot

Are you 100% positive the posts that are showing up are his, and not someone elses?

What search type are you using? The vB search of Fulltext?
