A BRAIN-DAMAGED man, who was later killed by his mother, sustained his injuries from jumping out of the back of an ambulance, a coroner ruled.

But in his narrative verdict, Dr Edward Thomas, said that Thomas Inglis, 22, was persuaded rather than consented to be taken to Queen’s Hospital in Rom Valley Way, Romford, with a police escort after being injured in a pub fight on July 7 2007.

His mother, Frances Inglis, of Dagenham, injected him with a fatal dose of heroin at a Hertfordshire care home on November 21 2008, for which she is currently serving a five-year jail term.

She had made a similar but unsuccessful attempt on his life in Queen’s, two months after he fell from the ambulance - believing him to be trapped in “a living hell.”

Paramedics failed to use a ‘capacity tool’ to determine whether Mr Inglis was capable of consenting to go to hospital in light of his head injuries, the coroner found.

Neither Mr Inglis or paramedic Madeline Basford-Herd were wearing seatbelts, contravening London Ambulance Service (LAS) guidelines.

A light on the driver’s console to warn whether the ambulance’s rear doors were open was also not working.

The coroner ruled, had it been working, the driver might have decelerated the first time the doors opened.

An LAS spokesman said: “We have looked into this incident to identify what we can do so that something like this does not happen again.”
