A couple who have lost three of their sons to London's murder epidemic have told of their despair at the capital's spiralling levels of violence.

David Bello-Monerville, 38, became London's 62nd murder victim this year when he was stabbed to death in Barnet last month.

Shockingly, it later emerged that his brother Joseph had been killed in Hackney six years ago, and another of his siblings, Trevor, was murdered in 1994.

The three brothers' devastated parents, John and Linda, have now spoken of their desperation, having done all they could to keep their children away from the carnage playing out daily on London's streets.

They said the latest murder has been like 'a terrible dream' for them.

In 2017, Linda Bello-Monerville appealed for information about the second killing of one of her sons. A third son, David, has since been killed in violence in London. She is pictured with Jonathan, her surviving son

Mrs Burke-Monerville told The Guardian: 'I was a teacher and always taught my children the value of education. I don't understand why this keeps happening to us... Why can't we have peace? Why couldn't our children be allowed to grow up like other children?'

The family had previously sent Joseph and his twin Jonathan to boarding school in Nigeria to keep them away from crime and they insist none of the family have ever been in trouble with the police.

David, the most recent son killed, had been campaigning for justice over the deaths of his brothers, the killers of whom have never been found.

John Burke-Monerville added: 'We are asking ourselves what is happening to the younger generation... As a grieving family we would like to know: when will this violence stop?

'After so many years of pain and sorrow I cannot believe that this has happened to us again, that once more a wonderful son has been taken from us.'

David had just got a new job at the time he was brutally killed, his family have said

David had just started a new job, one of two positions he worked to support his two sons, and his family said 'everything was falling into place for him' at the time he was killed.

The 38-year-old died after blades, chains and broom handles and brandished in a fight near his family home in Barnet.

His mother was seen sobbing desperately at the scene, screaming: 'Not another son!'

Three men have been charged with aggravated burglary over his death and the family hope they will finally see one of their sons' killers brought to justice.

Joseph Burke-Monerville was shot at in his car in Hackney in 2013. His brothers David and Jonathan were in the car at the time but survived.

Joseph's case was believed to be one of mistaken identity after it was claimed the gunman believed they were from a different housing estate.

The first brother to be killed, Trevor, was attacked by five men in 1994 and died from his injuries.

A total of 78 people have been killed in London this year, with fears knife crime is now spreading to other cities around the UK.
