Task 5
1 Debbie Whorton, Kathy’s sister, had never believed the
verdict and she asked Royce Toney to re-open the case
when he became head of the department in 2003. He
agreed to do so because he remembered the doubts he
had had at the time.
2 The new team found the original five or six suspects plus
the anonymous 911 caller who had originally reported
finding the body, but who was never traced at the time.
3 The perpetrator was a career criminal with previous
convictions for sex offences called Anthony Wilson. DNA
evidence left at the scene of the crime was submitted
to CODIS (The FBI’s DNA database for the whole of the
United States – CODIS stands for combined DNA index
system) and there was a positive match with Wilson’s
records.
