PID in BASH

In a shell script, in need to execute a proccess in background, do some jobs then kill that process. ie,

someproc parameter1 &
somescript.sh
kill pid_of_the_proc_in_the_first_line

How can can get the PID of the process I'm invoking in the first line?

someproc parameter1 &
myPID=$!
somescript.sh
kill ${myPID}
