The killer nurse injected patients with drugs to stop their breathing to satisfy his lust for excitement. Speaking through his solicitor, Geen insisted he was innocent and would appeal against his conviction.
Geen gave a total of 17 victims injections of drugs such as muscle relaxants, insulin and sedatives to stop them breathing.
The court heard how Geen looked elated as his patients went into respiratory arrest and even boasted to one doctor, "There is always a resuscitation when I'm on duty".
David Onley, 77, from Deddington, died on 21st January, 2004, and Anthony Bateman, 66, from Banbury, died on 6th January, 2004. Fifteen other patients recovered shortly after they developed breathing difficulties.
Benjamin Geen was told he would serve at least 30 years for the offences
committed at Oxfordshire's Horton General Hospital between 2003 and 2004.
