New details emerge on man accused of murdering Silverwater Prison inmate

A man accused of killing an inmate inside a maximum-security prison in Sydney's west has been deemed too troublesome to be transported to court.

The accused killer, who Seven News can't name, is allegedly as violent as a career criminal can get, seen in CCTV footage knocking out a woman with a baseball bat inside a supermarket.

On Sunday, he was charged with the murder of Silverwater jail inmate, Alfredo Pengue.

Days earlier as prisoners mingled in G-Block, surveillance cameras captured the alleged killer outside Pengue's cell, yelling, "I will f****g kill them all”.

Pengue returned shortly after but the 45-year-old followed him in, closed the door, then left 26 minutes later.

Another inmate found Pengue unconscious and hit the emergency button.

Seven News understands he had head injuries and severe strangulation marks around his neck.

When formally questioned, the alleged killer allegedly told police, “I know what I’m here for, I’m not talking to no-one.

“Just hurry up and do the charge. I want to go back to my cell so I can go to sleep."

Typically, when someone is charged with murder, they would be physically transported to court to face the charge in person.

However, Seven News has been told a risk assessment on the prisoner made it preferable that he remain locked up at Silverwater.

A letter to the Attorney-General, leaked to Seven News, shows police would have resisted offering an escort to court, “finding the prisoner transport practice unsustainable, as it continually and consistently removes vital police resources”.

The matter is due back in court on March 28.
