I found a news article about murder from the London Old England newspaper, London, Middlesex, UK. It was dated May 23, 1840. On page 3, it said:
The mere reader of the Paris journals would not be thus impressed, for they rarely copy accounts of murders from the provincial journals, unless they were attended with extraordinary and romantic circumstances.
