January 1889, six women die in Managua in a similar way to five in London in autumn 1888. Number "6" and word "Agua" are traces. There are bodies of water at distances of 6, 60, 600 and 6000 km, with "knife" coded twice. Code name Carl Feigenbaum (Carlos, Charles) should possibly lead to the name, place and product of a German company. A group photo of the workers in 1892 shows a man with a knife and a sailor's cap, elegantly shabbily dressed, left-handed, around 55 years old, who could match the drawing of Anton Zahn in 1896. He is probably Jack the Ripper.
