On Saturday, December 7, 1811, shortly before midnight, Mr. Marr, a respectable linen draper, closed his shop at 29, Ratcliffe Highway, in Wapping, East London, and with his young assistant began to replace on the shelves the goods which had been displayed for sale during the day. The household consisted of Mr. Marr, his wife and child, the shop-boy and a maidservant. At about twelve o'clock he sent the maid to a nearby shop to buy oysters for supper. She left the door open but on returning she found it closed and rang the bell. She rang again, but there was no reply. Joined by a watchman an hour later, they both rang and knocked until a neighbour, noticing that the yard door was open, leapt over the fence and entered the house. There he saw a terrible scene. Marr and his assistant lay in the shop, dead, with fractured skulls; Mrs. Marr's body was in the passage, also battered about the head, and the child had been murdered in its cradle. The ripping chisel of a ship's carpenter and a maul were found lying near Marr; bloodstains reddened them and spattered the window. No property had been stolen: indeed about one hundred and sixty pounds in cash and notes were found in the house.
