She might have written them herself but I'm sure LE would have discovered it by now.
Even if aspects of the letter are true, the anonymous writer is a coward of the worse kind. If someone has a grievance they should own it, imo. I wrote a letter to my foster mother, it wasn't nasty or full of foul language, but I had to tell her how her actions and abuse affected my childhood and life. She probably threw it in the bin but no matter, writing the letter had a cathartic effect on me, she was finally out of my life. I had/have no intentions in terrorizing that woman, I'm not HER!
I have very strong feelings about self righteous people who anonymously harass and stalk others, sometimes, purely based on gossip and hearsay. They enjoy the fear and anxiety they cause their victim knowing they will never be held accountable. They sit back and watch the fire, like an arsonist enjoying his handy work, and when it finally dies out, they reignite it.
Sorry for the rant. :blushing:
