Aaron French-Willcox was 19 years old when he died.
He was homeless and was living in a tent in a park in Cardiff.
It was mid-February and temperatures had plummeted to below freezing.
Aaron had found himself living in a shelter after addiction and family problems left him without a proper roof over his head.
He struggled with life on the streets.
He was bullied, and retreated beyond the help of those who loved him.
His family described Aaron as 'playful' and was 'always making people laugh'.
Aaron had also recently become a father himself.
For the first time, Aaron's brother and sister spoke to ITV News about how their brother became a victim of the growing problem of homelessness - and how such a young life ended in tragedy.
Rhys and Briony went back to find the place they believe Aaron was living - and ultimately where he died.
In a small wood, old food packaging, as well as drug paraphernalia can be seen on the ground.
Aaron was suffering with Type 1 Diabetes and was resuscitated in hospital shortly before his death.
According to an eyewitness, staff were heard to comment on Aaron's frail condition.
He weighed just six stone when he died.
"I wouldn't want another family to go through what we've been through. I didn't know bad it could hurt until it actually happened. You can't imagine it", said his brother Rhys.
Aaron's family want to do more to help people who find themselves in a similar situation.
Sister Briony is now working with the homeless in Cardiff because of what happened to Aaron.
"We should be listening to their stories instead of judging. Not everyone is a drug addict. Not everyone chooses to be homeless."
A full inquest into Aaron's death is due to take place next month.
