You're used to seeing Susanna Reid sitting alongside Piers Morgan nearly every morning for ITV's Good Morning Britain. The two like to have a joke, as morning TV presenters do, as they wade through the news and topics making the news.
But you'll see a completely different side of the 47-year-old when the network airs Crime & Punishment: Children Who Kill. The title is pretty self-explanatory, the journalist will interview people who have been locked up for murdering someone when they were just a kid.
One chilling interviewee is Morgan Leppert, who was described as a 'baby-faced teen' who was sentenced to life imprisonment for killing a 66-year-old man in a robbery-turned bad. She was spared the death penalty because she was just 16 when she was convicted.
When Susanna and Morgan come face-to-face, the murderer has some pretty ominous things to say.
"I'll probably kill myself, honestly," the now 24-year-old said as she smiled at Susanna . "No hope. I would end it. and it sucks and it's sad but it's true."
Morgan is trying to get her sentence overturned, adding that she blames her boyfriend, who was with her at the time of the murder, for her current predicament: "I thought I had the perfect boyfriend. But he turned out to be the monster who took my life away."

That's just one of the terrifying individuals Susanna meets during the documentary series, which she says had a profound effect on her mental health.
She referred to another interview, where she spoke with Joshua Phillips, who murdered his eight-year-old neighbour when he was just 14.
"I've been affected by all the documentaries I've done but the thing about this is the child who was murdered was so young," Susanna tells the Sun.
"I was in tears doing the interviews – and I found everything about meeting Phillips upsetting, distressing and heart-breaking.
"I have never been as distressed as I was filming that documentary."
She says the first thing she did after filming the episodes in America was hug her kids. To be fair, it would be pretty difficult sitting next to a convicted murderer and listening to them talk about the crimes.
Phillips says he killed his young neighbour because she copped a baseball to the eye and couldn't stop screaming. He smacked her over the head with a bat three times to shut her up, before stabbing her 11 times in the chest and neck to finish her off.
The series will air tomorrow at 9pm.
