Superintendent Paul Yeomans said autopsies had been completed and confirmed the gunshot wounds suffered by 10-month-old Hunter, four-year-old Koda and their 34-year-old father.

Police had previously revealed that a rifle was recovered from Little’s car.

Supt Yeomans said the investigation was still ongoing and issues including domestic violence and mental health would form part of a report to the coroner.

A statement from Little’s wife Melissa has also been released in which she says words cannot express the pain she has felt since the tragedy on Monday.

“Damien was my childhood sweetheart who became my loving husband. He was also a father who loved his two children very much,” she said.

“Damien valued and appreciated our close-knit family, he put us first, we were his whole world.

“He spent every hour providing quality time and teaching the boys how to live and grow.

“Damien, I loved you so much. You have left a huge hole in my heart, our memories I will cherish forever. You will not be forgotten.”

Melissa Little said her wish was for her husband to be remembered as a well-respected and valued member of his family and the community.

She said the loss of her two young boys had left her heart broken.

“I will miss them and think about them each and every day. Their futures were full of endless possibilities,” she said.

“Koda had the biggest heart, so loving and caring. He always loved a hug, had so much enthusiasm and was a willing helper.

“Hunter was such a happy, content and smiling baby. His laughter was infectious and his cheeky little personality was just beginning to emerge.”

As she continued to grieve, she also asked for privacy as she came to terms with the “unexpected and tragic event”.
