A diabetic man who overdosed on insulin was in debt over drugs, had quit his job and was in rent arrears, an inquest heard today.

Craig Oxlade, 30, who had type one diabetes, was found unconscious in his room at the YMCA in Crest Road, High Wycombe on February 2.

Craig Blake, a housing support officer at the YMCA, discovered him on the floor of his room and said he was making “strange noises.”

Mr Oxlade was taken off life support at Wycombe General Hospital on February 5 after doctors declared his brain was severely damaged by the overdose and he was unlikely to recover.

At an inquest on Wednesday, a statement from Mr Oxlade's sister Deanna said he was “not very accepting of his [diabetes]”, did not manage it well and would threaten to overdose when he argued with his partner of almost 12 years, Kayleigh Collis-White.

Ms Oxlade said: “Kayleigh kicked Craig out of their flat and he eventually moved to the YMCA. They had two children together and Kayleigh would threaten to stop letting him see his children and he thought the best thing to do was end his life. I always thought he was serious about it.”

The court also heard how he had recently quit his job at Tyre Team in Naphill, owed drug debts and was in rent arrears at the YMCA.

DC Tim Robins, from High Wycombe Police Station, said Mr Oxlade may have quit his job because he was going to be sacked for running up debts and “may have been stealing tyres from work” while his bosses had paid off a £1,100 drug debt when someone turned up and demanded it.  

In a statement read out to the court, Ms Collis-White told how the couple would regularly argue over money and in the days before he overdosed, had argued about money he had stolen from them.

He then sent a number of messages and pictures of six insulin pens and of his legs with needle marks. In his final message, he said “I told you I would do it.”

Ms Collis-White said: “Craig would have worried about the drug debts and stealing, all of that would have played on his mind. He seemed to have a lot of problems but didn’t know how to deal with them.”

David Bailey, pathologist, said the cause of death was hypoxic brain injury and bronchopneumonia due to hypoglycaemia.

Crispin Butler, senior coroner, concluded that Mr Oxlade did commit suicide.

He said: “There were issues that were clearly burdening him, the job, the debt, the relationship issues and his children. There were a number of factors burdening him that all seemed to arrive at the same time.”
