Deputy assistant coroner Mary Burke recorded an open verdict after an inquest into Tracey Ann Wileman’s death.

The divorced woman’s body was found at her home on Chequerfield Drive on March 4.

Wakefield Coroner’s Court on Friday heard the 41-year-old suffered from type one diabetes and had been admitted to hospital in the past after a hypoglycemic attack when her blood sugar was low.

Neville Outibridge, coroner’s officer, said Ms Wileman called her ex-husband Stanley Wileman and told him her blood sugar was high and she had given herself an insulin injection at around 9.20pm on March 3.

Police officers found her body the next morning after Mr Wileman raised the alarm when he visited her home and received no response.

The inquest heard two notes in Ms Wileman’s handwriting were later found – but it was not clear when they had been written.

Pathologist Dr Patricia Gudgeon, who carried out a post mortem, said she was unable to acertain a cause of death, but there were indications she had been unconscious for a period of time and her blood sugar was low.

There was no evidence of an overdose or natural disease.

Recording an open verdict, the coroner said: “Did Tracey undertake a intentional, deliberate act that cause her to take an excessive amount of insulin? We know that at some time she was low in mind, but we do not know if this was immediately prior to her death. Did she make a mistake? Did she actually take too much insulin?

“After the hyperglycemic incident on March 3 did she subsequently develop a hypoglycemic incident?”
