Nurse jailed for life for murdering and poisoning patients

Self-styled 'angel turned evil' Victorino Chua has been jailed for at least 35 years for murdering two patients and poisoning 20 others.

A nurse found guilty of murdering two patients at a hospital where he worked has today, Tuesday 19 May 2015, been sentenced to life in prison with a minimum of 35 years.

Victorino Chua, aged 49, of no fixed address, deliberately contaminated products that were stored on acute treatment wards at Stepping Hill hospital with insulin.

The products - which included saline bags and ampoules - would then be used by unsuspecting staff members to treat unsuspecting patients.

The insulin would cause them to suffer hypoglycaemia - a drop in blood sugar levels.

The effects of such poisoning vary drastically but can result in death and Chua was found guilty of the murders of Tracy Arden, and Alfred Derek Weaver, known to his family as Derek.

He was also found guilty of intentionally causing grievous bodily harm to one patient who suffered a brain injury as a result of being poisoned and for whom Chua falsified his medical records, recording him as being conscious and alert when blood tests have proven that he was suffering severe hypoglycaemia.

Chua was also found guilty of attempting to intentionally cause grievous bodily harm to 21 other patients who became unwell after being treated with products contaminated with insulin but for who it could not be proven beyond all reasonable doubt suffered injury as a result or who suffered no lasting effects.

In the case of one of the patients, Chua was seen by staff to give a false reading by placing his own finger in a probe that records patient information.

Stepping Hill Hospital

A police investigation commenced in July 2011, after a number of patients fell-ill and contaminated products were discovered.

Officers from GMP’s Major Incident Team commenced an investigation into the poisonings and contaminations. The main lines of investigation included a review of hospital data, including point of care results, medical records and preserved blood samples, a review of the supply chain of effected products and an investigation into the shift patterns, backgrounds and working practices of hospital staff.

Due to the ongoing inquiry, Chua changed tact as he sought to poison other patients - again indirectly - in January 2012, by altering patients? prescriptions.

Alterations involved adding prescription only drugs or increasing the size or frequency of the dose.

One patient was actually administered a dose prior to the alterations being discovered and subsequently made a full recovery.

In respect of these offences, he was found guilty of eight offences of unlawfully administering or causing to be taken by another person any poison or destructive or noxious thing with intent to injure, aggrieve or annoy, or attempting to do so after deliberately altering prescriptions.

Of all employees, including permanent, temporary and 'bank' staff, detectives established Chua was the only person on shift proximate to three key events. He was present when five patients were poisoned overnight between 10th and 11th July 2011; when contaminated ampoules were found overnight between 11th and 12th July 2011; and when prescription charts were fraudulently altered on 3 January 2012.

During a search of his house following his arrest, detectives recovered an autobiographical letter penned by Chua. In it he wrote, “I’m a nice person but there a devil in me- I’m evil at the same time angel,” and: “So I’m writing this letter in case something happen to me my family can continue my case or can tell somebody to look at it and work out how and angel turn to an evil person. The bitter nurse confession. Got lots to tell but I just take it to my grave.”
