Yes, I can use it, but I can't figure out the process ID. I am trying
to understand the man page on this to kill the group 67, or www.
Obviously, I can't figure out the proper use of that syntax here.
Man said
The following PIDs have special meanings:
-1 If superuser, broadcast the signal to all processes; other-
wise, broadcast to all processes belonging to the user.
-pgid Send the signal to all processes within the specified pro-
cess group.
You are confusing user group (i.e. www) with process group (i.e. logical
grouping of processes for job contol, etc..).

See ps(1) and termios(4)
note: termios had the most descriptive explanation of process group
under Job Control that I could find in a few minutes. There probably is
a better man page.
I do not know a way to find process group without forking. An
alternative (if you could not determine process ID) desperation move
would be kill -1 as root (it should not kill system processes according
to kill(2))
