Peter Steers complained to his wife that he was ill, and wanted to be bled, and despite such facilities being available locally, he walked the seven miles to Knutsford. After a drink or two he went to see a Mr Bellingham, a surgeon and apothecary, who bled him at his request, and gave him an emetic. He told the surgeon that his name was Heald, and that he came from Mobberley. (Interestingly he used the name Heald as that was the name of Mary Heald, who poisoned her husband in 1763, and was also a quaker).
He had told another witness, Sarah Barrow, that he wished his wife was dead so that he could be with her.
On 20th November, Peter Steers made some firmaty for the family. His wife Phoebe complained that hers was not good, and she only ate a small amount, but died soon after.
15 days after her death her body was exhumed, and according to Mr Bellingham, the same surgeon who sold Steers the poison, she died of arsenic poisoning, the same poison he had sold Peter .
It took two minutes to find him guilty at his trial, and he was sentenced to be hanged and anatomised
