In May 2017 49-year-old builder Michael McGrath disappeared - almost without trace.

No crime scene was ever found. No weapon was ever found. No body was ever found.

So how could his longtime friend be arrested and charged with murder?

In February 2023, the trial of David Charles Benbow finally began. Benbow stood accused of murdering McGrath because he’d started a relationship with Benbow’s former partner, Joanna Green.

The prosecution said that, while based entirely on circumstantial evidence, its case was so comprehensive there could be no doubt Benbow was guilty.

The defence said detectives were biased, working hard to build a case against Benbow after he was identified as a prime suspect - by Green.
