 Wagner was said to have been unhappy about the births of his children and complained about the financial stress of feeding his family; he was seemingly indifferent to the interruption of his birthday in 1909 by infant Rudolph's death.Some time in 1906 or 1907, thinking that the people from Mühlhausen had passed on their knowledge about his crime, the feelings of being ridiculed and watched by others returned, and as a consequence he began to make plans to take revenge on those whom he deemed to be the cause of his misery, the villagers, and especially the men, of Mühlhausen.In autumn 1907 he bought the first Mauser pistol, the other one following in 1909 and, with his bicycle, which he loved more than anyone or anything else, he made extensive journeys through the surrounding area and sharpened his shooting skills in remote forests.
