Former prison worker found guilty of raping inmate in Adelaide

A former prison worker has been found guilty of the rape and aggravated indecent assault of a female inmate at an Adelaide jail.

Enio Screpanti, 67, stood trial in South Australia's District Court for four days after pleading not guilty to the offences, which occurred in the early 2020s.

After just over two hours of deliberations, the 12-person jury delivered unanimous guilty verdicts to the charges.

Screpanti's family became audibly and visibly emotional as the jury's verdicts were read aloud.

After the verdicts, prosecutor Christine Hanna asked the court to revoke Screpanti's bail due to the seriousness of the offending.

Screpanti's defence barrister Gilbert Aitken opposed the application, but Judge Anne Barnett said it was appropriate Screpanti be remanded in custody and revoked his bail.

In closing submissions earlier on Monday, Ms Hanna had told the jury the victim was a "credible and reliable witness".

The jury previously heard Screpanti sexually assaulted the woman on a treadmill in the prison gym before raping her several months later after asking "[her] to come to a shed as they had a job to do".

Convicted murderer, and fellow inmate, Nicole McGuinness also gave evidence in the trial about uncharged acts that were brought before the court to give context to the charged offending.

"On the prosecution case that evidence still has a part to play in your [the jury] consideration and deliberations on the charged acts," Ms Hanna said in her closing address.

"It might also help you to understand that the alleged charged acts did not come out of the blue."

In his closing submissions on Monday, Mr Aitken stated there was no CCTV vision of the incident and had told the jury the victim's evidence was "less than satisfactory".

Screpanti will return to court next month for a pre-sentence hearing.
