Are you sure you want this hack?

Who is the parent of your running squid processes?

From how your start script reads it does not at all look like you should be
using --enable-kill-parent-hack.

Hmm.. your shutdown script seems rather odd. Most likely caused by the
oddness of "squid -k shutdown".

"squid -k shutdown" only tells Squid to shut down, it does not wait for Squid
to shut down. It if failed to tell Squid to shut down (most likely not
running, or the pid file has been trashed) then it will return false, else
true.

To make a foolproof Squid "shutdown" you need to

squid -k shutdown

if successful, wait for a while. suggested up to 2 minutes or until the last
Squid process disappears.

if Squid processes remains
  log a warning
  kill -TERM any remaining squid processes
  wait again
  kill -KILL any remaining squid processes just to make sure..
endif
