Alexander McCartney, an online predator from south Armagh, who targeted children across the world, has been jailed for a minimum of 20 years.
The 26-year-old from Lissummon Road in Newry's actions led an American girl and her father to take their own lives.
12-year-old Cimarron Thomas from West Virginia in the US took her own life in May 2018, rather than comply with his demands.
He's pleaded guilty to 185 charges in total - including manslaughter - in what's thought to be the UK's worst case of catfishing.
Catherine Kierans is from the Public Prosecution Service for Northern Ireland.
She spoke outside court afterward:
"This little girl was one of thousands of victims of McCartney's abuse around the world. He has caused immeasurable damage to children and their families."
