The explosive device that caused a motorcycle to explode in the driveway of a Menasha home last month is believed to have been a quarter stick of dynamite. John Wallschlaeger, Menasha police community liaison specialist, said the bomb squad can’t say for certain but suspects the device planted on the motorcycle was a quarter stick of dynamite or something similar because of a lack of wires or a timing device. a quarter stick of dynamite, or an M-1000, has an explosive mixture that can cause severe bodily injuries or even death when exploding near a person. the case has gone quiet as the complainant has not returned calls to provide police with further information about potential suspects.
