Three doors down: a murder, a mother and a thirty year investigation

In May 2023 David Boyd was found guilty of the brutal murder in 1992 of seven year-old Nikki Allan. Sharon Henderson, Nikki’s mother, called for a public inquiry into why it had taken the police so long to find and convict her daughter’s murderer.

When Nikki was murdered, Sharon was a single mother of four living in Wear Garth, a rundown housing estate in Sunderland. David Boyd lived a few floors above Sharon in the same block. He was known to the police. He was the kind of offender who should have been caught.

Three doors down tells the astonishing story of Sharon Henderson’s thirty year campaign to get justice for her daughter’s killing. It shines a light on police behaviour and their treatment of working class women. It’s a personal tale of trauma and resilience in the face of systemic police failure, that couldn’t be more timely.
