Scam caller

I received a message from a woman named Sabrina Reed who called from 310-691-5840
She said that she was calling in regards to a case that was being filed through the Los Angels County the case wasn't being file agents me but it was agent's my son. She said that she was instructed to make me aware that my name and number have been listed as a known relative and or associat of my son and that it appeared that my address was also listed as a place of likely location for my son. She then went on to say that at this point my son still had the legal right to contact the proceeding office that is processing his case, however once the case was filed that will no longer be an option. The phone number provided for that legal department is 1855- 208-3988 and it also states that when he calls he is to provide  his case number ###### then you just hear the loud click.
I tried calling the number back and no answer.
I also used goggle to look up the number she called me from and the call back number she said to call.
THIS IS A SCAM!!!
