Father Who Horrifically Abused Daughter Jailed For 33 Years

A 74-year-old man who raped and sexually abused his daughter in Sydney so horrendously she developed thousands of identities to cope will likely die in jail after being sentenced to at least 33 years.

Richard Haynes, whose attempt to retract his mid-trial guilty pleas was rejected, was sentenced in the NSW District Court on Friday for abusing his daughter, Jeni, from 1974 to 1981.

Judge Sarah Huggett sentenced him to 45 years with a non-parole period of 33 years, meaning Haynes couldn't be released until he was 104.

Jeni has been diagnosed with dissociative identity disorder and has some 2500 personalities.

Haynes was extradited from the United Kingdom in February 2017 to face dozens of charges of rape, buggery and indecent assault against his daughter, Jeni, in the 1970s and 1980s.

She was aged between four and 11 at the time and was later diagnosed with dissociative identity disorder, previously known as multiple personality disorder.

He pleaded guilty to 25 offences in March and will be sentenced by Judge Sarah Huggett on Friday in the Downing Centre District Court.

At Haynes' sentencing hearing in May, Jeni said she had waited decades to "smack" her father in the mouth over his abuse.

She looked across at her father - who smirked and stared down in the dock for the hearing - and declared: "Scum."

"He heard me beg him to stop, he heard me cry, he saw the pain, the terror he was inflicting upon me," she said, reading from her victim impact statement.

"He saw the blood and the physical damage he caused and the next day he chose to do it all over again."

Her father's sexual abuse forced her to develop the thousands of personalities as the only way to cope, including "Muscles" and four-year-old "Symphony", two of the 33 identities she embodied while giving evidence.

Jeni has a permanent colostomy bag - which she described as a "degrading, daily reminder" of her father's crimes - and permanent issues with eyesight, hearing, dentistry and mental health.

She feared birthdays, relationships, men, bathrooms and even enjoying food.

Media required Jeni's permission to report both Haynes' name and the nature of his crimes as doing so would identify her as a child victim of crime.
