Three people have been found guilty of killing teenager Ben Kinsella.
Ben's death hit the headlines after he was stabbed last year. It sparked big protest marches calling for people to stop carrying knives.
Juress Kika, 19, Jade Braithwaite, 18, and Michael Alleyne, 20, were convicted of killing Ben.
Ben died after a row broke out involving some of his friends while he was on a night out to celebrate the end of his GCSE exams in London.
Knife crime has been in the news a lot, but it's important to remember stabbings are very rare.
Ben was the brother of actress Brooke Kinsella, who used to star in EastEnders
