On Friday the shattered local community gathered to mourn their loss, while police try to work out what went so tragically wrong.

“He was such a loving and caring young man who had his whole life ahead of him.

“We thank you for all your thoughts and continuous prayers at this time.”

Police are now calling for witnesses to help them piece together exactly what happened in the moments leading up to the tragic crash.
