I just read the letter and she indeed called it a gathering comprised of herself and 4 others and the four others were all male.
So she was the kind of girl who went to parties at unknown houses solo, but can’t remember how she got there either?
But she remembers the names of all four young men perfectly and thinks it was 1982.
To my mind she’s lying outright.
P.S. A competent prosecutor would take her apart on this fact alone.
