In a crowded hall in the Sicilian town of Messina, a 17-year-old girl with dark hair stands on a platform, gripping a microphone.

In front of her, an audience of around 100 kids and their teachers.

I can assure you that losing your mom when you're only 9 years old isn't easy.

I wanted to grow up with my mom. She used to say, when I'm a little old lady, who will I have to help me?

And I used to say, me, me, I will. I'll push your wheelchair for you and your sick.

But that's never going to happen because they took her away. I don't know where she is. I want an answer.

I've been waiting for one for years.

The girl, Latice, is here to bear witness.

Her mother, Maria, is thought to have been murdered by the Indrangata, one of the most powerful criminal organisations in the world,

based in Calabria in southern Italy. After her speech, she told me what happened the day her mum went missing.

One morning, it was May 2016. Mum had to go up to her farm. I was asleep.

My sister woke up just as mum left the house. Mum saw her, said good morning to her, and then she left, saying she'd be back in a bit.

She'd arranged to me to work me at the farm. A while later, the workman called my uncle and said that the doors of my mum's car were wide open and the engine was running.

He said there were traces of blood and some of her hair inside the car. There was no other trace of her. Nothing.

There was a camera that could have filmed the incident which was right in front of the farm. At the gate, except it wasn't working that day.

It had been tampered with so it couldn't record anything. We don't know what happened to mum.

Police still don't have a definitive answer, but in the run-up to her disappearance, an alleged organised crime boss

had been putting pressure on Maria to sell him her land and she'd refused.

An informant later told the authorities Maria had been kidnapped and killed. Her remains fed to farm animals.

Her daughter's testimony is part of a broad campaign across southern Italy. To prevent young people joining the world of organised crime,

the world of the Sicilian Mafia, the Camora in Naples and the Indrangata based in Calabria.

The Mafia, the Indrangata, the Camora, they're not just a bunch of violent people. There's more to it and they're invisible.
