Deletion of all files owned by specific owner

[D Hull <dbhull1 () hotmail com>]

This evening, all of the files owned by a specific user were removed from a server, including the user's home directory 
and files owned on an NFS mounted partition.

I did not have any baselines in place to help troubleshoot this problem so I am starting from scratch and don't have 
much to go on. I realize I am in a bad spot. I am able to recover the data. I need to be able to determine what 
happened though - as best as possible under the circumstances. Any suggestions would be greatly appreciated.
