Netflix is set to broadcast a crime series examining the unsolved murders of four young Northern Ireland women over a period of more than 40 years.
The deaths of Lisa Dorrian, Inga Maria Hauser, Arlene Arkinson and Marian Beattie are revealed in detail in The Murder in The Badlands as their families continue their search for answers and justice.
Initially broadcast on BBC One NI, a global audience will now be able to watch the four part series which forensically rebuilds the time-line of the murders of the four women and the investigations that followed.
Each episode features insights from surviving family members, police officers, journalists and criminologists.
