The parents of baby Chloe, allegedly killed in her babysitter's care, have finally spoken about their trauma.

“Why didn’t you tell me she had asthma?” was the first question babysitter Ketapat Jenkins asked Anthony and Kat Murphy when they returned from a long-overdue date night to pick up their daughter, Chloe.

But baby Chloe didn’t have asthma. Her struggles to breathe, her limp and unresponsive form, and her subsequent death were caused by injuries “similar to those of a car crash victim” – injuries caused while in the babysitter’s care.

Ketapat Jenkins was arrested and accused of dropping Chloe, or shaking her with such force to cause her death, but she pleaded not guilty.

Jenkins claimed Chloe was already sick when she was dropped off at her home, and that her injuries may have been caused during an argument between Anthony and Kat two days prior.

After a lengthy trial in 2014, Jenkins was found not guilty of Chloe's murder.

Now, devastated by the loss of their daughter and the legal system's failure to bring her killer to justice, Chloe's parents have spoken to Sunday Night for the first time.

"When you see your baby girl open her eyes are look at you, it's indescribable," Chloe's doting father Anthony reminisces.

"She was such a beautiful, gentle soul."

When Kat and Anthony realised their baby girl's life was quickly coming to an end, their world came tumbling down.

"To hear those words come out of the doctor's mouth, it just blew me away. That was the last thing I was expecting. Every step of the way it just got worse and worse and worse and worse."

Kat and Anthony were forced to give the order to turn of Chloe's life support after doctors gave her no chance of survival.

"T0 actually say the words to end your child's life... that was one of the hardest things I've ever had to deal with," Anthony told Sunday Night.

"Watching them turn the machines off was the most horrible moment of my life."

"No parent wants to see their child die before them," Kat says.

But the trauma for Chloe's parents was far from over, with justice being denied time and time again, first at trial and then again in coroner's court.

"To get to that point and hear a verdict of not guilty [for Ketapat Jenkins] was devastating," Anthony said.

"We went from inconsolable to angry."

"Watching my daughter be denied justice. It's just not right."

"She's done it, no doubt in my mind. But there's not much we can really do about it."
