Sherri claims that her mother, Betty, lied to her her entire life about the identity of her biological father. Sherri says she thought the man who raised her was her father, but when she was 21, she received a letter from a little girl who claimed that they shared a father, Wayne – a different man than the man who she believed was her dad. She says she confronted her mother, who she says denied the claims and then snatched the letter and hid it from Sherri for 15 years.
