According to a probable cause affidavit, a woman in Lexington, Kentucky, called police after finding her stepdaughter's diary and reading an entry, written in letter form and addressed to Pridemore, in which the girl wrote, "You raped me for about three years".
Pridemore had lived with the child and the woman in Boynton Beach and would "forcibly have sex" with the child when her mother was at work, police said.
Boynton Beach police spokeswoman Stephanie Slater said in a news release that the stepmother of the 13-year-old girl now living in Lexington, Kentucky, came across an entry in her diary in May that accused Jackson Pridemore of raping her during those years.
