New Netflix True Crime Documentary Tells Shocking Story Of Dad's Mission To Avenge Daughter's Death

In 1982, French teenager Kalinka Bamberski died in the house of her stepdad, renowned German doctor Dieter Krombach.

German prosecutors ruled the death of the 14-year-old was accidental, but disturbing autopsy results led her dad André to believe that Krombach had raped and murdered her.

In My Daughter's Killer, André reflects on his remarkable battle for justice, which spanned the best part of three decades.

The grieving dad battled to get the doctor sent down, but Germany closed the case and denied Krombach's extradition to France.

But after an unrelenting campaign by André, Krombach was tried in absentia in France and convicted of manslaughter.

Still, Germany denied extradition, and with years of tireless fighting proving unsuccessful, the statute of limitations in France - which dictated that convictions could not be brought after 30 years - got ever closer to running out.

Resorting to one last desperate measure, André arranged for Krombach to be kidnapped from his home and dumped outside of the prosecutor's office in Mulhouse, eastern France.

The case shocked the world and André was found guilty of organising the kidnapping - but in 2011, 29 years on from Kalinka's death, Krombach was finally convicted and sentenced to 15 years behind bars.

A synopsis for the new documentary reads: "My Daughter's Killer explores the limits of justice, abuse of power in the medical profession and the widespread indifference to crimes committed against women.

"In-depth interviews take us on Bamberski's journey, as he reveals the lengths he went to to try and bring Krombach to justice, whether it was flyering Krombach's hometown or alerting the authorities, everything in Germany failed. And although a trial in France found Krombach guilty, the German authorities refused to extradite him.

"Over the years other women accuse Krombach of assaults and rape, but he faces no charges for Kalinka's death and in a chilling TV interview, he reveals his complete lack of remorse towards his accusers.

"Finally in desperation in 2009, Bamberski takes matters into his own hands. This 70-year-old accountant decides he needs to get Krombach to France where there is a warrant for his arrest. On 17 October 2009, Krombach is found outside Mulhouse courthouse, bound and gagged.

"Two years later, in October 2011, he is finally convicted for the death of Kalinka. But it has taken a father 29 years, a brutal abduction and even his own conviction for the kidnapping to get there. Speaking in the film, Bamberski reflects on the toll of his pursuit and how he did it all for his beloved daughter Kalinka."
