THE family of a 13-year-old who died after being found unconscious in a park have urged parents to speak to their children about drugs, and asked anyone who has information about his death to speak out.

They spoke after a vigil was held in Ystrad Mynach Park, where Carson was found on Friday evening (April 12).

Carson’s mother, father and brother were at the vigil, where hundreds of balloons were let off into the sky in his memory.

Speaking afterwards, the family spoke of how their lives where "changed for ever" by the tragic events of Friday night.

“Carson was bright and caring, kind and loving," they said.

"He was a cheeky little boy. He was the best big brother to Coby and was loved by so many.

“From the bottom of our hearts, we’d like to thank all those that have taken the time to leave messages of condolences. Hearing your fond memories of Carson has brought us comfort during this terrible time. We have been truly overwhelmed by the support we have received locally, nationally and from around the world.

“Today, we as a family, along with Carson’s friends and the Ystrad Mynach community, have been able to celebrate the short life of our beautiful boy who we will all miss so much and it has given us great comfort to see all those who knew and cared about Carson come together this afternoon. We’d like to thank Carson’s friends for organising such a thoughtful tribute, I know they all meant so much to him.

“Thinking of another family going through what we have is unbearable. We urge people to talk about the devastating consequences that drugs can have and how they destroy lives. Parents, please speak to your children, or if you are young and need help, there are people that can give you advice.

“If anyone can help find those responsible, please come forward. Someone, somewhere must know information which could help. However small the detail may seem, please get in touch with Gwent Police to help them with their investigation.”

Superintendent Nick McLain from Gwent Police has previously said he believes someone sold the teenager illegal drugs.

A 14-year-old has been arrested today on suspicion of supplying class-A controlled drugs.

Gwent Police have asked people to refrain from "harassing, threatening and abusing people" online in the wake of the tragedy.
