The Murder of Logan Mwangi 

“It is probably one of the most concerning calls that police will ever deal with, missing children. You know instinctively that any one of them could be the occasion where something tragic has happened.” Mark O’Shea, Chief Inspector, South Wales Police

This extraordinary documentary tells the story of the investigation into the murder of 5-year-old Logan Mwangi, whose body was found dumped in a river just yards from his home.

With remarkable access to South Wales Police homicide detectives, the programme captures the arrest and police questioning of Logan’s mother and her partner, alongside the painstaking work to prove who killed him. 

The documentary hears from Logan’s biological father, Ben Mwangi, who speaks openly on what it is like to lose his son, as well as his discussions with the police on what happened to Logan. Mr Mwangi last saw his little boy 19 months prior to his death, as he was stopped from seeing him by Logan’s mother, Angharad Williamson.

The documentary shows the chronological order of events, from the 999 call to the final court case. The behind-the-scenes footage follows every step of this harrowing story - one of South Wales Police’s biggest investigations. 

The case, led by Chief Inspector Mark O’Shea and Detective Inspector Lianne Rees, shows first-hand the dedication - and the emotion - of those police officers as they try to deliver justice for Logan and his family.
