Delete Duplicate Cronjobs

I set up same cronjobs in two different users to generate messages at 5:30 AM
Not Its generating duplicate messages.
I want to delete the cron entries set up in the first user, but I am unable to view the entries in that user.
I tried to find the process Id, but its not showing any id

Could anyone help me with a solution?

Thanks in advance

Nskworld,
If you are unable to view/delete the cron entry, here are a few options:
1) Rename the shell script that sends the message, so that when the other
user tries to run it, an error message will appear and no message will display.

2) Change the user's path not to access the shell script.

3) Rename the existing shell script and empty it, keeping the executing
permissions -- the other user will continue to run it and nothing will happen.

Thanks.. I ll check this on monday and get back to you
