On Thursday Jade Braithwaite, 18, Juress Kika, 19, and Michael Alleyne, 20, were found guilty of murdering Ben Kinsella.
The 16-year-old schoolboy was stabbed 11 times in York Way, Islington, and died shortly after.
In a victim impact statement read out to court, Ben's mother Deborah Kinsella described how the murder has affected their lives.
I make this statement and the feelings and emotions are felt by all my family but no amount of words could ever express the daily pain we feel for the loss of Ben.
Deborah Kinsella says her life will never be the same again
On 29 June 2008 our beautiful son Ben was brutally and savagely stabbed to death. We as his family have been left devastated and in total despair.
Our whole world has been totally turned upside down. Ben went for a good night out and never came home again.
Ben had only just finished school - a straight-A student, he had a job and had got his place in college (he never learnt of the wonderful exam results he had achieved and worked so very hard for).
Ben loved life, he loved living and he had so much to live for. He knew where he was going and where he wanted to be.
Ben loved nothing more than to make people laugh, he was a fun-loving, happy-go-lucky boy with a heart of gold and would do anything for anyone. A testimony of this was his funeral that was attended by so many friends who filled the church and pavements outside.
Ben loved art and wanted to be a graphic designer, he loved his family, cooking, football, music and girls.
The people who murdered him knew nothing about our Ben, not a hair on his head, a bone in his body, not anything about our wonderful son. They had never met him before or spoken to him - they just cruelly took his life away with knives for no apparent reason.
We had brought Ben up to always walk away from trouble. This sadly cost him his life. He walked away to get safely home and they took advantage of that - he was one boy on his own. It seems unfair their intent was to stab someone that night.
We were a big, happy, loving family (we are one down, one missing). We are hard-working and just wanted the best for all our children in life. There are now just three of us at home.
We have had to move house because it broke our hearts to not see Ben in his bedroom curled up sleeping and safe in his bed. We so miss Ben's love and laughter and most of all the boy thing in our family.
Ben was our precious son that we cherished and were so immensely proud of, and by the way we had brought him up.
He had values and respected everyone he met. We as a family will never know the man he would have become, the wife he would have met and the children he would have had.
This has all now been taken away from siblings, his grandmothers, aunts, uncles, cousins, friends and us.
No parent or sibling should ever have to go through or see what we have seen with our son. He died in front of us, we then had to visit him in a morgue, the undertakers and finally to bury him.
We can now only visit Ben at a cemetery, our beautiful son who so loved life.
We cry every day for the loss of Ben, we do not sleep like we did before. Nearly a year on our nights are still filled with nightmares, of our son's last moments and what he went through that fatal night.
Our lives will never be the same - we have all been so deeply affected.
We as a family will never get over the loss of our Ben. We are just trying to get through it. Our family now face a lifetime of feeling this way.
Nothing we can say or do will ever bring Ben back. All we can hope and pray for is that justice will prevail, maybe then we can find some form of closure to this awful event that has devastated our family's lives.
