27

Craig Steven Marshall, 19, is the 27th teenager to be murdered in London this year. He was stabbed at the foot of a block of flats in Acton, West London - a few minutes walk from where I live.

Following his knifing on Thursday night, he managed to get himself to Acton police station, just around the corner from Rufford Tower. He died on Friday.

His best friend, Steven Mingard, said: "Craig was a really good person. We'd just made a pact to grow our hair long and he had finished a painting and decorating apprenticeship."

In 2007, 26 London teenagers met with violent deaths.
