Student Hanna, now 17, has fond memories of Samuel and says she misses him every day.

She said: “He was my brother, my friend, he was everything to me. Everyone who met him fell in love with him instantly.

“I was just so lucky that he was my brother.”

Samuel, who lived with his family in Stratford, was walking on a patch of parkland at the junction of Chesterton Road and Upper Road at around 3.20am on Saturday October 23 2010.

It is believed two gunmen appeared behind them dressed in black with balaclavas and fired four shots.

Hanna recalls: “I remember hearing my mum scream in the next room and I ran in and said ‘Mum, mum, what’s the matter?’

“She’d thrown the phone down on the floor.

“So I picked it up and it was his mate saying Sam had been shot. It was a real shock and he died right there that night.”

Samuel had been shot in the chest and was pronounced dead at the scene.

His 15-year-old friend was hit in the stomach but went on to make a full recovery.

Officers arrested four men aged between 20 and 23 the following month but they were released without charge.

But Hanna says police cannot take further action without witnesses or more information.

She said: “I don’t think it’s about being brave, it’s more that, if it was a member of your family, just think about how you’d feel if you had to go through what we’ve been through.

“Just think what it would be like if you knew someone was sitting at home who knew something but they didn’t say anything.”

Det Sgt Gary Royal, investigating, said the Met’s Operation Trident are committed to finding Samuel’s killers and urge anyone with information to call the incident room at West Hendon on 020 8733 4211 or Crimestoppers anonymously on 0800 555 111.
