Dedea Redanies was convicted in 1857 for the murder of Caroline and Maria Back. It evidently was an infamous case as although the crime occurred in Dover the article in question comes from a Sheffield newspaper.
Here are a couple of extracts from the article;
“As a proof of the singular character of this man we have been favoured with the sight of a little memento he gave to a man appointed to watch over him.”
These 'mementos' were drawings of the murders which I have included below.
Typical Victorians to turn a news article about an awful crime into an art review!
