The mum of a man who was killed after he was punched at a music festival has vowed to get justice for her son following the tenth anniversary of his death.

Elaine Hart's son Robert, 26, died days after he was struck by an unidentified attacker in a row at Parklife Festival in Heaton Park, Manchester in June 2014.

Greater Manchester Police (GMP) have never found his killer, despite a £50,000 reward for information being put up earlier this year.

Elaine lives in Macclesfield.

Speaking on the ten year anniversary of her son's death today (Tuesday), Elaine, 75, has pleaded for anyone who has information about the attack, to come forward.

Elaine, who kisses Robert's photo every morning, said: "Every single day - I just ask why?

"His killer is still out there, enjoying his life - maybe he's travelling or has a family - and he's living the life that Robert should be living. He took that life away.

Greater Manchester Police released this appeal, as the festival took place again last weekend.

"Please, if you have any information that would help - contact the police because it's now been ten years.

"You have no idea of what me and my family have been going through.

"Nothing changes, life goes on but it's not the same.

"You just exist because every single minute of every day, I look at Robert and I think of Robert and I go out and think of where it was.

"He never leaves my thoughts and my mind - I think my boy should still be here."

Robert was stood with his girlfriend waiting for Snoop Dogg to come on the main stage when a blow-up doll hit her face and left her covered in dirt.

He is buried, like many Maxonians, on Prestbury Road.

An altercation broke out, which resulted in Robert losing consciousness but he was helped to his feet after CPR was performed.

The injuries which Robert sustained as a result of the attack were far worse than first anticipated and he was taken to hospital, where he died on June 11.

Elaine said: "My son went that weekend to enjoy himself - they didn't go to cause any trouble and they didn't go to be aggressive.

"They went to listen to music and to enjoy the weekend and Robert never came home.

"He now lies in Macclesfield Cemetery but he should not be here - living his life just like the man who attacked him.

Robert's attacker is described as mixed race, in his mid-20s, around 6ft to 6ft 2in tall, muscular build with short, dark hair which was shaved at the sides.

The area of the incident circled.

He may have been with an unknown woman, who was white, in her mid-20s with blonde, shoulder-length hair, around 5ft 7ins tall and possibly wearing a pink T-shirt.

Elaine said: "He apparently walked away from the crowd, with a blonde-haired girlfriend who pulled him away.

"He didn't say - he walked away after punching Robert.

"He saw him hit in the ground and he walked away.

"The crowd went to help Robert and he walked away.

"Witnesses say they saw him later on but he went somewhere that night and got up the following morning and the day after that and the week after that.

"There's no question that people do know who he is."

Elaine, of Macclesfield, Cheshire, has also paid tribute to Robert - saying remembering their memories together is what helps her get through life.

She said: "The memories of Robert, and how much I loved him and how much he loved me help me get through life.

"The only way is to remember such a kind person, who was helpful.

"Everybody loved Robert and everybody thought he was such a lovely person - he wasn't aggressive.

"He was always happy to help people and loved meeting people and he loved life - that's what he loved, he loved life.

"He loved to travel and be with people - he was such a nice person to know.

"He attended quite a few festivals but that was the first one at Heaton Park.

"If he couldn't afford the tickets at university because he was a student, then he would work on the gates and then he could listen to the music.

"He had three guitars and loved music."

Detectives have urged people to 'dig deep into their consciences' and come forward.

DI Madeline Kelly said: "Even though this terrible incident was almost 10 years ago, it will still be fresh in the minds of many people, especially Robert's family and people who were at Parklife.

"Despite the passing of time, the heartache felt by Robert's family has not faded.

"Just as we were in 2014, we are determined to catch the person responsible which is why we are appealing for the assistance of the public.

"We are appealing for people to dig deep into their consciences – if you were one of the people involved on the day we would urge you to come forward.

"No-one went to the festival that weekend with thoughts of violence."
