Man on trial for two murders had already been convicted of killing his cellmate

James Desborough denies two murders near St Austell. But while waiting for that trial in jail, he strangled his cellmate and was convicted of it in March 2026. Prosecutors told the jury this as accepted fact. Desborough admits he hid the victims' bodies but says he did not kill them. The case raises questions about how prisons decide who shares a cell.
