CONVICTED killer Helen Ryan, serving at least 27 years in jail for arranging the murder of her husband Jeffrey Ryan at Duri, faces more criminal charges.
Tamworth detectives have laid additional charges against Ryan, who was found guilty last year of arranging a hit man to execute her estranged husband three years ago.
Ms Ryan, 52, was sentenced to a maximum 36 years' imprisonment late last year for her part in organising a hitman Kenneth Brooks to kill Jeffrey Ryan at his Duri property in October, 2009.
Now Ryan is facing an additional charge in relation to the murder events.
Tamworth detectives met with her last week and charged her with perverting the course of justice.
Police have confirmed that a woman has been accused of tendering false information while under oath.
The charge is believed to relate to evidence Ryan gave to a court during a bail application prior to her conviction for murder.
A summons relating to the charge calls for her appearance at Burwood Local Court on July 17.
Meanwhile, in other court proceedings, Ryan has until next Friday to meet a deadline in the Court of Criminal Appeal for her appeal over the murder conviction.
She had launched legal action to claim a part of Jeffrey Ryan's estate to fund that appeal and a NSW Supreme Court judge ruled earlier this month that she should be allowed access to some funds up to $242,000 to allow her to seek legal advice and fund the appeal.
The determination on that figure has not yet been made.
The July court appearance relating to the latest criminal charge is expected to be short and Ryan should appear via video link from her prison site. The hearing would expect to indicate a subsequent date to examine the brief of evidence.
