A man accused of murdering two other people while awaiting trial is also alleged to have killed a fellow inmate at HMP Exeter in Devon. Prosecutors tell a jury that James Desborough, 40, attacked and killed inmate Steven Kempster, 65, in September last year at the prison. The account presented in court states that Desborough killed Kempster in his bed. The jury is therefore considering allegations that Desborough, while facing charges related to the earlier murders, committed an additional killing inside the prison.
The case is being heard after Desborough was charged over separate incidents involving the deaths of two other people. As the trial progresses, jurors are expected to weigh evidence relating to both the prison killing and the earlier alleged murders. The reporting also identifies the prison location as HMP Exeter and places the alleged cellmate killing in September, with the trial proceedings ongoing at the time of publication.
