Someone I barely knew 34 years ago tracked me down & is mailing increasingly desperate letters. Legal options?
Location: California
In the past 2 months I have received a series of 6 snail mail letters from someone that I worked with very briefly 34 years ago.
Background: I worked with this person for approximately 3 months back in the early 90's. We were cordial but not close by any stretch... never spent any time with them outside of work, never talked about my personal life with them. I had completely forgotten about their very existence until these letters started arriving.
Facts:
They live across the country from me.
They are the same sex as me (I am no gay or bi).
The letters are increasing in terms of desperation but have not been out and out threatening. They have said things like, "I know this is you so why are you not replying to me" and "I won't stop until you talk to me" and "I think I'm in love with you."
I do believe it's them, they described themselves, our manager, and other details, plus sent a picture of what they looked like back then.
I have their facebook (which is basically empty), their phone number and mailing address. I have these items because they've provided them in the letters.
I have not responded in any way, nor do I plan to.
Since they are across the country from me and haven't made any threats, I don't think a police report is in order, but the repeated contacts and rising level of desperation still puts me a bit on edge.
QUESTIONS: Would it be legal to hire an attorney to send a one time, strongly worded cease and desist? Is that even a thing? Or should I just continue to ignore?
Anything else legally I could or should do?
