Claire Burt, a friend of Jordan, who described him as a "wee brother" to her, said he was "the nicest kid".
"He was my neighbour's best friend and they would always come over an see me and my partner, so he was like a wee brother to both of us," she said.
"He was one of the most kind-hearted people I have ever met. I could talk with him for hours and he would always make me feel good about myself.
"He honestly was the nicest kid. I never heard him talk badly about anyone and he would always be asking people if they need a hand with things and no matter what age you were he would treat you like you were his best mate.
"He would go out of his way just to make sure I was ok.
"He will be missed by so many because he touched everyone he came across."
Several of Jordan's Facebook friends have been writing messages on his page.
Zara Poi-Walker said she couldn't believe he had gone.
"I just wish it was a bad dream and someone's gonna pinch me and I'll wake up and you'll still be here! I just wish we had more time together, you were such a loving boy and it breaks my heart to see that your gone! Taken away far to early Jordan!!

Timaru Boys High School rector Nick McIvor said Jordan was an "energetic, popular boy" with "a quick smile and positive personality".
"He was a very happy boy who enjoyed the company of others; with a close and supportive circle of friends.
"Jordan loved sport, especially his rugby, and time down at our skate park with his mates
Extra support was being provided by the school's guidance network for boys who might find it difficult to come to terms with Jordan's death, Mr McIvor said.
"Our students, staff and community are deeply saddened by this loss," he said.
"Our sympathy and thoughts are with Jordan's family and friends.
"Jordan will be greatly missed by all who knew him."
The support was initiated with a special Year 9 and Year 10 assembly this morning and would be ongoing. Students families have been sent a statement to inform them of the event, Mr McIvor said.
