Pretty much any lethal booby trap will send you to prison.
`Research and read about the subject and laws regarding MAN-TRAPS - those using lethal or deadly force are absolutely illegal and verboten in the U.S., and elsewhere around the world. Man-traps of even the non-lethal type have been illegal since 1827 in England, except for the hours from sunset to sunrise. FYI

I believe in CA a set gun will earn you a first degree murder charge. If that is the million dollar question, do not call me as your expert.
I would be willing to be a large coffee at Starbucks (that’s a big money bet in my league) that almost every DA in CA will charge you with first degree although may accept a plea to a lesser included offense to move the calendar along.
