South Australian police are unlikely to lay criminal charges against Michael Guglielmucci over the fake cancer donation controversy.

The Advertiser understands that Mr Guglielmucci is in hospital receiving psychiatric care after confessing to faking a battle with terminal cancer to hide his 16-year obsession with pornography.

The wife of fraud pastor Michael Guglielmucci has vowed to try to save their marriage, despite the humiliating revelations of his cancer hoax and pornography addiction.

She has turned to a counsellor to help cope with her husband’s massive deception, which has shocked not only his family’s church, Edge Church International, but the world-wide Christian movement.

Michael Guglielmucci spent two years playing to packed houses on the Christian rock scene, sending an anthem of faith and healing to the top of the charts.

But last week the Melbourne-based pastor came clean about the terminal cancer he did not actually have. [video]
