removing locks or rolling back transactions

I am having trouble removing locks from an oracle 8.0.5 database. One of my users aborted their session in the middle of it while it was holding locks on certain objects.
I have since killed the session manually using the alter system kill session command.
Even thought these sessions are marked as killed in the v$session view there are still active transactions mapping back to each one of them. These transactions have left eachother in a deadlocked
state. I cannot find the correct docementation on either releasing locks or forcing a transaction to rollback or commit. Killing the transaction would be okay too.
Can anyone help me out on the commands I am looking for?

thanks in advance
Steve
