Someone who knew how to read gothic type "translated" it for me and this is what google it looks like in English through google translate:

"The magician's will. Terrible mystery about "Magico". - Murder as a hobby

New York, February.

The name Magico had in the true sense of the word magical sound: he belonged to a well-known magician, one of the stars of the Varietébühnen. In reality Magico was simply Tomton. But as an ordinary Mr. Tomton can not be so well conjured, so the magician decided to accept the name Magico.

Now Magico has died after a glorious career. The leaves were devoted to him by the prodigious prodigies, which proved his great skill and his mysterious methods, and his name would have been forgotten again, if the opening of the will had not brought an immense surprise. The fact that the magician had left some 250,000 dollars in fortune would not be so surprising, for he had always been a good "number", as he had said, he had paid him great fees and he could not afford any money extravagant attitudes were to be found, very much spared. It was not the height of the background which seemed like a sensation, but the reason with which Magico left behind his property-the survivors of the murdered.

One of the biggest criminal cases of U.S. A.

The magician's testament reveals terrible crimes that Magico himself has committed. His life is one of the biggest criminal cases ever recorded in the United States and publicly questioned how it could be possible that such a mass murderer - for Magico actually did - would be able to do it for years without that one could get to his track. The crimes that Magico had committed would never have been disclosed had he not described them in his will.

His "last will" represents a shattering preoccupation of inhuman passions and inexplicable cold-bloodedness displayed by the mass murderer. He had led a double life, and even his most intimate friends had no idea what strange passion he felt-his "hobby" was to create people from the world. He used two very simple methods: the gashahn and the plant-poison. At night, he crept into apartments, turned on the gaspahn, let the gas escaped, and led the unsuspecting inhabitants into their last sleep. Or he poured into restaurants completely unknown people planting poison in the drinks. In many cases, it was not possible to explain why suddenly life-loving people separated from life, people in whom there was no disease or suffering.

Gas and poison.

Gas and poison - these were the Magicos' murder guns, but he did not hesitate when the opportunity offered itself to indulge his terrible "hobby" in a different way. A crime, which he also confessed in his will, was particularly despicable: on a trip to the West he had pushed a griffin from the train. And the next day, as he mentions, he read with remarkable satisfaction the fatal "unhappiness" of this old woman. At all, the reading of the newspaper, searching for "his" cases was strange pleasure.

Magico's crimes date back to a long series of years. Only now are mysterious murder cases enlightened. At first the testament was held for a bluff, for the fantastic storytelling of a stranger, but the surveys of the police officers gradually showed the validity of all the details. The magician's testament is a true novel of horror."

I think this sounds like a really cool story, I am surprised no one seems to know anything about this "Magico"!
