A health and safety officer took his own life after he became depressed by issues which included the fact a doctor was unable to treat his broken wrist, a coroner heard today.

Donald Chester, from West Wycombe, was going to become a father for the third time when he jumped off the top of the Easton Street car park last March and suffered fatal injuries.

Two months after the incident his pregnant wife had to take the tragic decision to turn off his life support machine and he sadly died.

The father suffered multiple severe injuries when he jumped from the 25ft high roof on March 28 last year, one week after suffering a severe emotional and mental deterioration triggered by an unsuccessful hospital appointment, the inquest at Beaconsfield heard.

Mr Chester had broken his arm at work weeks previously, which had forced him from his job as a site excellence assistant for some weeks. He was attending an appointment at hospital on March 22, senior coroner Crispin Butler was told.

The 36-year-old fell into an emotional spiral with the fear he would not be able to support his pregnant wife and their two children, aged one and three years and even became stressed paying for a taxi to the hospital, his wife Susie said in a statement read to the hearing.

However, he was informed by his doctor that he would not be treated that day as his arm was still in a plaster cast – and he made his first attempt to jump from the car park roof.

He was talked down from the scene by officers and negotiators after his wife had tracked him down.

Mr Chester’s mental health continued to spiral as he worried he could not support his family, battled alcohol abuse and was haunted by the death of his friend two years previously, he told doctors after being Sectioned under the Mental Health Act following his attempted suicide.

The coroner was told that he also felt unsupported by his employer, was unhappy with statutory sick pay and was struggling to sleep but he was co-operative with mental health professionals and agreed to a further management plan to aid his symptoms.

He was sent home around midnight the same day, the inquest heard.

However, just days later was rushed to Stoke Mandeville Hospital in Aylesbury, after taking an overdose in a second attempt to take his life, Mrs Chester wrote in her statement.

He was detained there and treated after mental health professionals deemed him to pose a further risk due to his history of impulsive and self-destructive behaviour during periods of stress.

The coroner was told that Mr Chester suffered a history of suicidal thoughts, depression and low moods and had a history of self-harm including cutting his wrists and alcohol abuse – and had briefly gone missing in December 2015.

Working as a site excellence assistant at Bidfood UK in Slough, the father was allergic to wheat and was admitted to Stoke Mandeville Hospital after suffering an anaphylactic shock, from which he discharged himself on December 30, 2015.

The inquest was told that by March last year, his mental health nose-dived once again and by the evening, he was fearful of the three-week wait he would have to endure before his anti-depression medication began to take effect, Mrs Chester told the coroner.

She said that her husband again began to threaten to kill himself and her sister Monica rushed to their home where she was able to calm him down, ensure he took his medication and put him to bed.

On the morning of March 28, Mrs Chester desperately “called around everyone” for help for her husband but was told the best available was an appointment in two weeks.

Later that day he was once again on the roof of the Easton Street car park and in an emotional final phone call he told his wife no-one could help him. He ignored the pleas of police officers at the scene and jumped from a ledge at 6pm on March 28.

He suffered multiple severe injuries to his head, skull and spine and was rushed to the John Radcliffe Hospital in Oxford.

However, Mr Chester succumbed to his injuries and passed away two months later on May 28.

Describing the events of March 27 in her written statement read to the coroner, Mrs Chester said: “Don was not good and hitting rock bottom, and he knew they [his medication] took three weeks to work. He wanted to be sectioned.

“Don was threatening to kill himself again. I phoned the out of hours team and a very angry man told me he couldn’t leave unless he left the house. My sister Monica came over, got him to take his tablet and put him to bed.”

Describing the following day to the hearing she said: "I phoned everyone to get help. The only thing they could offer was an appointment in two weeks.

“There was no answer and his phone location service was turned off. Finally he rang me and answered that he couldn’t do it anymore...by the time police got to me, other police got to Don. Police negotiators told him to get down.

“In our last phone call he was upset and said no-one could help him.”

Addressing the emergency services who came to her husband’s aid, she said: “I want to thank those from Thames Valley Police and the medical professionals who tried to save him, both at the scene and at John Radcliffe Hospital.”

Representing the family was solicitor Jessie while Neil McLaughlin represented the Oxford Health NHS Foundation Trust.

The inquest was adjourned until tomorrow (Thursday).
