A NURSE jailed for 30 years for murdering two patients and harming 15 others will tomorrow launch a fresh bid to quash his conviction.

Benjamin Geen, 29, of Orchard Way, Banbury, was jailed for life in May 2006 for two counts of murder and 15 of causing grievous bodily harm with intent.

He was found to have injected patients at Banbury’s Horton General Hospital with drugs to stop them breathing so he could enjoy the thrill of trying to resuscitate them, but has always protested his innocence.

The new attempt is the second time barristers working for the former Territorial Army lieutenant have tried to overturn his conviction.

A similar bid to have his conviction challenged as ‘unsafe’ failed in November at the Court of Appeal.

Today an online campaign was launched protesting Geen’s innocence.

His lawyers are expected to submit fresh evidence from a statistician to the Criminal Cases Review Commission.

Geen’s barrister is Mark McDonald, who runs the London Innocence Project, a non-profit legal and criminal justice centre.

Geen’s sister, Hayley Geen, 21, of Milton Keynes, said his family would not stop until they got ‘justice for Ben’.

She plans to set up a group on social networking website, Facebook, to gain support for the campaign.
