Guilty verdict in 'Evil 8' child rape case

A seventh man has been convicted of sexually abusing a 13-year-old girl who was pimped by her own father in Perth's so-called "Evil 8" case.

The father used online classifieds to arrange for at least six men to abuse her, mainly at their home in the city's north.

Five of them raped her while one of them, Benjamin Simon Clarke, indecently assaulted her and photographed her naked at an abandoned mine.

The father watched it all and also raped her while they watched.

Alfred John Impicciatore, 47, was the last of the men to face court and was the only one who went to trial.

He confessed to police about two months after the crimes in March 2015, but only entered a plea in November last year.

The case was adjourned many times after he failed to show up in court and changed lawyers, and he twice breached his bail conditions, fleeing to NSW on the second occasion.

Impicciatore finally had a brief judge-alone trial last week.

On Tuesday, District Court of WA Judge Mark Herron found him guilty of four counts of sexually penetrating a child.

Defence counsel John Hawkins had claimed his client admitted raping the girl because he was stressed, anxious, cold and tired after a long police interview.

But Judge Herron said he was satisfied beyond a reasonable doubt the confessions were truthful and reliable.

The judge said Impicciatore was initially reluctant to answer their questions because he was in the process of realising what he had done and facing up to it.

"It took him time to reconcile with himself what he had done before he was prepared to make full admissions," Judge Herron said.

During the father's online contact with Impicciatore, he asked for help with a South African man who had threatened to report the sexual abuse to police if a detailed wish-list of fantasies with the girl were not met.

That was former pastor Dawid Volmer, who stupefied her with an inhalant before raping her, and was jailed for 10-and-a-half years.

The girl capitulated to Volmer's demands, including wearing a blindfold.

The court also heard the father - who told police "it was fun while it lasted" - encouraged Impicciatore to stay overnight and "do it again" but he left.

The girl identified Impicciatore as the "chubby" man who had seen her chihuahua and said he had one too.

Impicciatore will face a sentencing hearing on March 26.

Eight men were initially implicated in the notorious case, but one of them was later found to have had no involvement.
