THE mum of murdered teenager Luke Campbell has opened her heart about his death and told how she keeps his bedroom exactly how it was as a shrine to her son.

Bournemouth University student Luke, 20, was killed by London drug dealers Larbi Mohamed, Saeed Alkadir and Delaine Brown, who are now serving life sentences.

Mum Hazel Hayes, who moved back from Bourne-mouth to her native Derby following the former Murray Park Community School pupil's death, has spoken about the experience.

The 52-year-old said she constantly asked herself how her likeable, hardworking and talented son met such a ''senseless'' death.

''I think it doesn't register with me a lot of the time. I still think he's going to walk back through the door," she said.

Hazel has kept Luke's bedroom intact.

James Bond and martial arts posters are plastered over the walls, while his clothes still hang in the wardrobe.

Hazel said: ''I have still got his room upstairs. Wherever I move, Luke has to have his own room with all his things in it. It's like he's still here."

Luke, who lived in Belper before moving to Burton, was only at university for six weeks before the attack. It is thought he was stabbed in a case of mistaken identity.

He died on November 7 last year and his killers were convicted last month after a trial at Winchester Crown Court.

Hazel said: "It was really difficult. It was all so senseless – it was nothing to do with Luke and Luke lost his life."

Hazel was very close to her son and her most special memories are of the ordinary things that happened every day – she and Luke play fighting on the sofa, laughing and joking.

When Luke's father died from the effects of MS, it prompted Luke to "work even harder," she said.

Hazel said that the trial resulted in a lot of mixed emotions. She found herself feeling sorry for Delaine Brown, whom the jury heard stabbed Luke.

''This is going to sound really awful, but I felt sorry for the one that did it. He just looked exactly like a normal boy.

"At one point he started crying. I felt guilty, I felt sorry for him. The other two – I just think they came across as evil."
