It appears John THOMPSON (called THOMSON in the trial report), who had been married to his wife for 20 years, struck up a relationship with a widow called Margaret CAIN or CANE and needed to get rid of his wife to be able to marry his mistress. He used chronic arsenic poisoning as the means to achieve his object, but in his attempt managed to eat some of the poisoned food himself as well as poisoning (although not fatally) the neighbouring household! The surgeon in attendance does not appear to have harboured any suspicions until after Mary THOMPSON died. The subsequent police investigation showed that John THOMPSON had not managed to cover his tracks in any way, and he was indicted with murder, found guilty and consequently executed.
Below is a list of all the people mentioned in the report of the trial (minus the barristers). Anybody with spare time could look them up in the census!
THE MAIN ACTORS AND THEIR RELATIVES:
The murderer: John THOMPSON (at times called himself John PEEL), age 42, millwright at RICHARDSON's yard, lived in Union Street, Botchergate, Carlisle, on the first floor. He mentioned a brother, but no name given.
The victim: Mary THOMPSON née ATTIS, age 43, wife of John THOMSON. Died on Saturday, 29 May 1847.
They were married on 06 May 1827 at All Saints Church, Newcastle on Tyne (exact date from IGI). They lived at Camperdown near Newcastle at the beginning of their marriage. They had one child, who died some years ago.
Mary THOMPSON née ATTIS had a sister who married Christopher WANLESS, an innkeeper at Camperdown near Newcastle.
Margaret CAIN (spelt CANE in John THOMPSON's confession), John THOMPSON's mistress. She was aged about 35 (estimate by the newspaper reporter) and had been widowed for 8 years. Her husband had been a weaver. They had three children, one of whom had died. Her eldest son John was aged 11. She initially lived in South George Street, then moved to Sowerby Lane just before harvest in 1846. In about April 1847 she moved to Irving's Court, Botchergate (to a room rented by John THOMPSON for her), but moved back to Sowerby Lane in June or July 1847. She did harvesting work and otherwise worked as a capmaker, as well as having frequent male visitors (one witness alleged).
