Nurses Who Kill

The series begins by examining the case of Allitt, a nurse on the children's ward of a hospital in Lincolnshire. She poisoned a string of young patients under her care over the course of 59 days in 1991, murdering four.

Benjamin Geen worked as a nurse at Horton General Hospital in Banbury, Oxfordshire. In 2006 he was tried and convicted of murdering two patients and causing GBH to 15 others but has always maintained his innocence.

Genene Jones worked in the paediatric intensive care unit of a Texas hospital.

Nurse Malcolm Webster was convicted for the murder of his first wife, Claire Morris. For 17 years it was believed to be an accident; until he staged another 'road accident' in New Zealand, involving his second wife, Felicity Drumm.

Anne Grigg-Booth, who was responsible for administering painkilling injections to patients, was a heavy drinker with a passion for drugs. We hear from the doctor that Grigg-Booth's team lined up as an expert witness in her defence. He was never to be called; Nurse Grigg-Booth killed herself.

Efren Saldivar confessed to killing 40 to 50 patients over an eight-year period. Quickly christened an "Angel of Death," he targeted patients who were already near death. Statistical analysis indicates that the total number of murders committed by Saldivar could be as high as 200, but the bodies were cremated after death long before he owned up to his deeds on the wards.

The case of care home worker Karen Pedley, who was given 14 life sentences in 2016 and found guilty of killing a 96-year-old resident by setting fire to her room.

The story of Sandra Weir, who acted as a carer for her elderly neighbour. But she was stealing from the pensioner to fund her drug addiction, leading to a tragic confrontation.

The case of New York paramedic Paul Novak, who boasted of committing the perfect murder after the dust had settled on the death of his first wife Catherine.
