Netflix has released the first trailer for The Disappearance of Madeleine McCann, set to premiere on Friday.

Madeleine, three-years-old at the time, disappeared almost 12 years ago during a family holiday in Praia da Luz, Portugal. She has since been the subject of numerous headlines, podcast episodes, books, and now the Netflix documentary.

According to The Sun, the documentary will claim Madeleine was kidnapped and has likely been kept alive by child traffickers because of her value as a “middle-class British girl.”

More than 40 people have been interviewed for the documentary including key figures who worked on the investigation.

Former senior police officer Jim Gamble – who was part of the UK’s first investigation into Madeleine’s disappearance – said he “absolutely believes that in my lifetime we will find out what has happened to Madeleine McCann. 

“There’s huge hope to be had with the advances in technology. 

“Year on year DNA is getting better. Year on year other techniques, including facial recognition, are getting better.

“And as we use that technology to revisit and review that which we captured in the past, there’s every likelihood that something we already know will slip into position.”

Madeleine’s parents Kate and Gerry McCann have refused to take part in the series.

They said in a statement earlier this week:

We are aware that Netflix are planning to screen a documentary in March 2019 about Madeleine’s disappearance.

The production company told us that they were making the documentary and asked us to participate.

We did not see – and still do not see – how this programme will help the search for Madeleine and, particularly given there is an active police investigation, it could potentially hinder it.

Consequently, our views and preferences are not reflected in the programme.

The Disappearance of Madeleine McCann will premiere Friday, March 15.
