Caught with child porn in jail cell

A SERIAL paedophile on the cusp of being released from Yatala Prison has been caught stockpiling child pornography in his cell.

A SERIAL paedophile on the cusp of release from Yatala Prison has been caught stockpiling child pornography in his cell.

Mark Trevor Marshall, who was labelled by Justice Margaret Nyland as "incapable of controlling his sexual instincts", was found in possession of unauthorised material on Wednesday.

His cell, in B-Division which houses general population prisoners, was then searched and more items, understood to be CDs holding child porn images, were found.

The matter is now the subject of police investigations.

"I can confirm that there was a search at Yatala Labour Prison involving a prisoner being found in possession of unauthorised material," Department for Correctional Services chief executive Peter Severin said yesterday.

"The prisoner's cell was subsequently searched, which resulted in a number of additional items being found."

Marshall has an extensive history of abusing children since June 1987 and in 2009 was jailed until further order by Justice Nyland.

"I am satisfied that at the date hereof the respondent (Marshall) is incapable of controlling his sexual instincts and is also unwilling in that there is a significant risk that he would, given an opportunity to commit a relevant offence, fail to exercise appropriate control of his sexual instincts," she said in her judgment at the time.

"At the present time there is a significant risk of the respondent re-offending and until appropriate treatment is provided to him the respondent represents a continuing danger to the community."

In July, Justice Nyland ruled Marshall could apply for release once appropriate accommodation was found, but he has yet to be released.

Marshall's family yesterday said they felt both shock and relief at the latest revelation.

Judith Jones, whose grandchildren were allegedly abused by Marshall, said the discovery should mean he is not released back into the community.

"If he can offend in jail, he can most definitely offend outside jail," she said.

"This is sick behaviour. Doing this shows that he cannot be rehabilitated and there's no remorse. He deserves to be locked up indefinitely."
