The Witness.

When Rachel Nickell was murdered on Wimbledon Common in 1992, André became a single parent overnight. Putting his own grief to one side, he made his son Alex – the only eyewitness to the attack – the centre of his world. Navigating the unscrupulous media furore and the urgency of an increasingly desperate police investigation, his sole concern became the welfare of his traumatised son. This is the story of how a father and son moved through the aftermath of unimaginable tragedy, from darkness into light.
