A teenager died three years after sustaining head injuries when stepping off a moving bus in Teddington, an inquest heard.

Today, his mother spoke of her relief that an inquest was finally held, more than a year after her son's death.

Alex Seaman was 19 when he opened the emergency door of a 281 bus in the High Street after missing his stop in April 2011 and jumped off while the bus was moving.

The brain injuries he suffered when he hit his head on a parked car left him in a vegetative state, West London Coroner’s Court heard on Monday.

Mr Seaman died on September 18, 2014 from multiple organ failure and sepsis brought on by a displaced PEG feeding tube and bilateral pneumonia.

The Richmond and Twickenham Times first spoke with Mr Seaman’s mother, Sally, in July when she spoke of her anguish about delays at the coroner’s court that meant the family had to wait more than a year for an inquest to take place.

Ms Seaman, a midwife, said eventually having the inquest had finally brought the family some closure.

She said: "It wasn’t something we were looking forward to but it is something we had to do."

Ms Seaman said senior coroner Chinyere Inyama was very helpful and fair during proceedings but the family did not receive a copy of the post-mortem report until a week before the inquest and until then believed Mr Seaman had died of pneumonia.

She said: "Even if we had had the post mortem a year ago that would have made life a lot easier."

Mr Seaman had been travelling back from Kingston on the 281 after celebrating a friend’s birthday and tried to get the bus to stop once it had gone past where he wanted to get off.

CCTV footage showed him lifting the emergency flap to open the door while the bus was still moving.

Mr Inyama said: "I see death every day. I rarely use the word tragic - but this was certainly tragic," the Evening Standard reported.
