Need to stop processes owned by different UID

I am running Solaris 9 on a V880.

I have two users, fred & barney, that have a need to stop a process even if it was started by the other user.

Example:

fred starts the process "watch_for_new_files"

barney needs to stop the process "watch_for_new_files", but it's owned by fred.

How can barney stop "watch_for_new_files" without switching user to fred or Super User?
