The heartbreaking story behind this photo of a dying kangaroo

A wildlife carer has recalled her heartbreaking discovery of a suffering kangaroo on the side of the road, left behind by the thoughtless driver who hit it.

Tanya Odonoghue, who works at the Warrumbungle Wildlife Shelter, was about 20 kilometres from home on Tuesday night after an 800km drive when she discovered the injured animal lying alone in the dark.

While other cars continued speeding past, Ms Odonoghue pulled over and tried easing the kangaroo’s pain as best she could.

“I sedated him to bring him home where he could be humanely euthanised,” she wrote in a post to the Facebook page of the Warrumbungle Wildlife Shelter, in the Orana region of western NSW.

“I was there in the dark, waiting for the valium to take effect, the odd car passing by, no one stopping to even ask if we were ok.”

That was until one man pulled over to ask if she was ok and what he could do to help.

“This kind young man offered to euthanise him for me, which he did,” she wrote.

“I don’t know who he was but I am very grateful to him for not only stopping to ask if I was ok, but to also relieve the suffering of that poor poor boy. Bless him.”
