Kevin IBBS
Perth resident Kevin Ibbs dubbed the '30 second rapist" had consensual sex with Christine Watson on the night of 29 November 1986.
Watson who was a close friend of Ibbs's wife, Katrina Carter, was at the time living in the same house as Ibbs and Carter. The sexual act was taking place with the full knowledge of Carter who was also in the house at the time.
As Ibbs was nearing ejaculation, Watson suddenly withdrew her consent to sex (so she later claimed) and then tried to push Ibbs away. Ibbs continued for a short time, approximately 30 seconds.
For this he was charged with sexual assault and found guilty under a law which had recently been introduced.
The judge in Ibbs case found that Ibbs had continued sexual intercourse for about thirty seconds without consent (for which he was later dubbed the 30-second rapist).
Judge Geoffrey Kennedy sentenced him to four years imprisonment.
Mr Ibbs appeal his convicted but it was dismissed. His sentence however was reduced from four years to six months.
Some years later Watson admitted to police that the whole incident was a set-up orchestrated by Carter to have Ibbs charged with sexual assault to get him out of the house they were sharing.
Christine Elizabeth Watson a.k.a. Christine Elizabeth Wardle and Katrina Ann Carter were subsequently convicted of conspiring to pervert the course of justice. They served seven months in jail.
Mr Ibbs' conviction was finally quashed in 2001 after this fresh evidence was presented however detectives would later confirmed that a body found under the Mandurah Traffic Bridge on Thursday night was that of Perth resident Kevin Ibbs who had sucided to his death.
