Dublin,

2016, a mother and father are accused of a crime against their daughter.

Garthy began this investigation after a child was treated for serious injuries in a children's hospital last year.

If you watch the CCTV, when we brought her to the hospital,

she wasn't crying, nothing.

Everything was normal.

Having gone to hospital for help, they end up getting arrested.

I cautioned her that she was not obliged to say anything unless she wished to do so.

The man who's 35 and the 25-year-old woman appeared before the Dublin District Court following their arrest.

What happens when you say the crimes you're charged with never happened?

In a case like this where the parents are consistently maintaining their innocence,

that can make the parents start to look like they're just not cooperating.

My name is Ruth Naga and from October 8th I'm going to begin telling you a story that will

make you question everything. For three years this couple signed on twice weekly for bail as their

children remained under a two slick hair order. Even my friends, who used to come to me, they run.

If I call them, they don't answer the phone.

And then the state puts you on trial, the first of its kind.

As soon as I hear, guilty, I know what it means.

That's the worst thing in my life.

And it feels like the whole world is against you.

Sentencing the couple, Judge Alma Sheehan, described the offence as the most egregious breach of trust.

The judge sentenced the father to five and a half years in prison and his wife to four years and nine months.
