The message is created when the kill signal is received. In case it was
an automatic kill. The core and message are usually not much use when
done manually.

Although in this case the problem actually could be related to what
Squid was doing at the time of kill. If a core exists you can use a
debugger (ie gdb) to load the core and see what Squid was doing when
killed. Otherwise you will need to wait for teh CPU to reach 100% again
and run strace on the squid worker processes PID to find out what is
sucking up the CPU cycles.
