Dean, who attended Newtownabbey Community High School, died aged just 16 last November.

He was found hanging from railings on the Limestone Road and died in hospital six days later. Dean hanged himself days after taking a number of ketamine horse tranquilisers at a party.

It is understood the pills, known as "blues" or "loyalist blues" are being sold as diazepam to young people in the area by paramilitary drug dealers.

Dean's death touched the hearts of seven Rathcoole teenagers, Natalie Carlisle, Megan Wray, Deena Osman, Rachel Stopford, Claire McCartney, Samantha McCallister and Samantha McCauley. They took part in a Girls Leadership Programme run by Rathcoole CEP and Challenge for Youth, and produced a DVD tribute in memory of Dean.

A special screening was held at Newtownabbey Community High, with Dean's heartbroken mum Alison attending the event.

Natalie Corbett from Rathcoole CEP said: "The girls chose to do this as it was something they felt very passionate about and Dean was a dear friend and classmate. The DVD focuses on Dean's life and the devastating, tragic days leading up to his death. It highlights the dangers of drugs and creates awareness around suicide. The girls have worked extremely hard to make this DVD a success; it was very painful for them at times."

In the film, Natalie Carlisle a classmate of Dean's says: "Not having Dean in school is just so different. He was like a class clown. He was bubbly and made people laugh all of the time. And because he is not there it is just different. The whole atmosphere is completely different."

She added: It's just been so tragic, what happened to Dean... I just hope it doesn't happen again to anyone."

The DVD also features an in-depth interview with Dean's mum Alison.

She gives a detailed account of the days leading up to her son's death and recounts the last time she saw him.

"He was sold drugs in the Tiger's Bay area," she said. "There were young ones selling them and there were middle men and suppliers, and the blues were still sold after Dean died.

"The drug dealers don't care. They don't care about Dean's family, they don't care about the other kids."

The grieving mum spoke of the final time she saw Dean: "We watched the Liverpool match on the Sunday and he fell asleep again. He went out, smiling away, he said I'll see you later mummy, and I gave him a couple of pound for a Chinese and I never saw him again. But he went out happy, but those tablets were still in his system. Apparently they make the kids so down they just want to die. His death has affected the whole family. There has been nobody arrested, no drug dealers arrested, and they still walk these streets

"If it had have been other areas Rathcoole, Ballysillan, the drug dealers would have been gone, but they are still here. The mothers know they are still here, the community knows they are still here and the kids know they are still here. But what can you do? It's up to the police."
The moving film also investigates the impact of drugs on young people and local communities.
