An engineer who fell to his death from a flat window in a 'tragic accident' has saved three people's lives through organ donation.

Jeremy O'Regan, 21, fell from a block of flats and was taken to hospital with catastrophic injuries on November 8.

After a week's battle, his family made the difficult decision to turn off his life support and donate his organs, saving three people who were in need of transplants.

His dad, Lee O'Regan, said the decision to donate his organs reflected the kind of person his son was.

Mr O'Regan said: 'We were led by what Jeremy would have wanted and there's no way he wouldn't want to help other people.'

Born on July 21, 2004, Jeremy was described by his father Lee, 48, mother Danielle, 45, and younger brother Andrew, 23, as outgoing, kind and well known across his home city of Southampton, Hampshire.

The father continued: 'Jeremy was the life and soul of the party. He'd start a conversation with anybody and always had time to talk to people.'

From school through to adulthood, Jeremy loved socialising and worked in bars around the city while building a career as a junior site engineer working on the Botley bypass.

Mr O'Regan said: 'He was just a really good-natured kid and had time for everyone.'

After the fall on November 8, Jeremy was taken to the Wessex Neuro Intensive Care Unit at Southampton General Hospital, where doctors carried out emergency surgery and kept him alive while his condition was monitored.

'For around about five days there was no change,' his father continued.

'The machines were breathing for him. They brought his heart back and his heart was keeping itself going.'

After scans and tests confirmed Jeremy had suffered catastrophic brain injuries, the family were told there was no hope of recovery.

Mr O'Regan said: 'The surgeon said, "Jeremy died a week ago.. We've got some magical systems keeping him alive, but there is no hope."'

When Jeremy passed away, the family were asked to consider organ donation. His father said the decision was guided by what they believed Jeremy would have wanted.

A letter later sent to the family by the organ donation team confirmed three people's lives had been saved as a result of the decision.

The father said: 'A gentleman in his 30s received a kidney transplant after being on the waiting list for four years.

'A lady in her 20s received a kidney after being on the transplant waiting list for three years. And Jeremy gave the especially rare gift of a heart to a gentleman in his 40s.'
