"After Waters’ conviction, his sister, Betty Anne Waters, sought to prove his innocence. She put herself through college and law school, all with the goal of exonerating her brother. In 1999, she located the Type O blood evidence collected from the scene of the crime and obtained a court order to preserve the evidence for possible DNA testing. In 2000, she began working with the Innocence Project on the case. Together Betty Anne Waters and the Innocence Project reached an agreement with the Middlesex County District Attorney’s office to allow a private lab to conduct DNA testing on the evidence. The results excluded Waters and the victim’s husband, proving that Waters was not the perpetrator."
