Quite simple: Much in the manner that mailing lists, and information about the finances of individuals are sold to commercial concerns, authors can purchase details of the life experiences of individuals. Being of marginal popularity and limited means, I buy story elements and characters from a discounter, Plot Lots, which deals in distressed, remaindered, damaged and irregular life stories. This may explain why you recognized familiar events in my story. I have a receipt, so I do not fear your lawsuit.
