Under cover of darkness, the brother and sister met Lefler, who gave Respa two suitcases full of dynamite which Kaltschmidt had smuggled piecemeal into Canada under the front seat of his automobile. Respa attached the clocks to the charges, set one of the infernal machines near the factory, and planted the other in the rear of the Windsor armory, in which Canadian troops were asleep, and near which was a Catholic girls' school. Then he and Mrs. Schmidt scurried back to the ferry and took the last boat to Detroit. At three o'clock in the morning they heard a muffled roar from the Canadian side; the factory bomb had gone off. The other charge failed to explode: Respa said he deliberately set the percussion cap at the wrong angle, because he knew that soldiers were sleeping in the armory, and he had no stomach for murder. One of the gang was presently arrested, and Respa was spirited away to the retirement of a mechanic's job in a West Hoboken garage. But he grew restless, and spent his money, and Kaltschmidt refused him more. He pawned his watch and his ring, bought a ticket to Detroit, and presented himself before Kaltschmidt with a demand for money, in default of which Respa proposed to "squeal." He was immediately returned to the payroll. The Canadian provincial detectives had begun to search for the night watchman, Lefler. They found him, and from him they extracted a full confession. Respa's arrest was easy, and the United States willingly returned him, although Kaltschmidt did attempt to establish a false alibi for his underling. Respa was sentenced to life imprisonment, Lefler to ten years, for the destruction of the factory. The dragnet closed in on Kaltschmidt. William M. Jarosch, a German-born, who later enlisted in the United States Army, had been introduced to Kaltschmidt in Chicago in 1915 by a former German consul there, Gustav Jacobsen. Jacobsen recruited two other men, and Kaltschmidt took the three to Detroit. Jarosch was directed to secure employment at the plant of the Detroit Screw Works, but he was rejected, so Kaltschmidt told him to watch the plant for a good opportunity to set a bomb there. In the course of his sojourn in Detroit he went to the Respa home in the placid little village of Romeo and returned with a generous quantity of dynamite. This he delivered to Neef, and in a conference at the magneto shop Kaltschmidt explained the operation of the time-clock, and ordered Jarosch to set the device at the Detroit Screw factory that night. He and his Chicago confederates set out for the scene, but there were guards about, and Jarosch had no desire for arrest, so he took the bomb to his hotel room, disengaged the trigger, and calmly went to sleep. Next morning Kaltschmidt reproached him, and Jarosch resigned, to return months later to show Federal officers where he had buried some 80 pounds of dynamite, nitroglycerine, and a bomb.
