kill him... and then kill all his children...

1. get his login shell from the /etc/passwd file and
2. then do a "ps -ef | grep <login shell>"
3. search for his id in the output
4. kill -9 <PID>

<edit>
You will also want to remove his ID if you don't want him logging back in.

#!/bin/bash
pgrep -u $1 bash|xargs kill -9

Will help you out do the steps above faster.
Just save is it as a script and run ./kick.sh username, and it'll log out the user, then you can create a lock file not to let any more logons.

That will work if all users use the bash shell. For the most part, this can be assumed on Linux. I just come from a UNIX background, where users use one of 3 major shells (Bourne, Korn, and C Shell).
