A Sydney doctor has been found guilty of injecting his wife in the buttock with fast-acting insulin so that he could be with his lover
Justice Clifton Hoeben ruled on Thursday that Brian Kenneth Crickitt had murdered his wife of 19 years, Christine Crickitt, late on the 31 December 2009 or early on New Year’s Day in 2010.
At the time of the event, Crickitt was a general practitioner at Campbelltown Medical and Dental Centre in the Greater Western Sydney region.
After investigations by police, it was discovered he was having an affair and in the weeks leading up to his wife’s death had spent most nights with his mistress, even raising the idea of marriage with her.
Police also discovered that on 30 December 2009, the day before his wife’s death, Crickitt had carried out two internet searches relating to fatal overdoses of insulin.
The judge concluded the only rational explanation was that he was seeking information to further his plan to murder his wife.
On 31 December, Crickitt saw a patient who was a diabetic.
That evening, the GP used a prescription he wrote for the patient to improperly obtain NovoRapid FlexPens from a local pharmacy, the judge found.
Rather than forcibly injecting his wife, the judge found it was more likely that Crickitt obtained his wife’s consent by persuading her it was a drug she legitimately needed.
Christine Crickitt had several health conditions and frequently relied on her GP husband to deliver medications, although insulin was not one of them as she was not a diabetic.
The drug would have led Christine Crickitt to experience incapacitating hypoglycaemia, eventually rendering her comatose and leading to her death.
Crickitt had initially lied to police, saying he had driven around for a few hours early on New Year’s Day after arguing with his wife, but later admitted he had spent the rest of the night with his mistress.
He also tried to cover up his actions by deactivating the NovoRapid prescription in his medical records.
An autopsy could not conclude the cause of the death, but the judge said he was satisfied beyond reasonable doubt that it was from an intentionally fatal overdose of insulin, due to Crickitt improperly obtaining the drug on 31 December.
Justice Hoeben said that Crickitt’s primary motive was a combination of increasing dislike for his wife and his infatuation with his mistress.
While the rational course of action for Crickitt would have been to end the marriage, Justice Hoeben observed that “of their very nature matters of love and hatred are not rational”.
According to news reports, Crickitt will be sentenced in February.
