escape, although his injuries seemed inconsistent with that version. Cole's supporter's argued that no revolvers or burglary tools were produced and that the motive was implausible. Nevertheless, no action was taken against Bennett or the other members of the posse. Natural gas boom Natural gas had been developed in Pennsylvania and Canada for some time, and had most recently been developed around Findlay, Ohio. In March 1886, a group of citizens, led principally by A.Y. Comstock (who had promoted the Frankfort and Kokomo Railroad) and D.C. Spraker (later President of Kokomo Rubber Company), circulated a memorandum seeking subscribers (at $100 each) for the purpose of boring for gas at a distance of at least below ground. It took until September to obtain the necessary 22 subscribers. The first rig was built south of Wildcat Creek. and on October 6, 1886, natural gas erupted forth and the well was capped. Together with the well in Eaton, which began producing slightly before Kokomo's, the discovery led to the Indiana Gas Boom. This discovery was directly responsible for Elwood Haynes' move to Kokomo, as a superintendent with a gas company with interests in Kokomo and Howard County. The Diamond Plate Glass Company (now part of PPG Industries) began in Kokomo in 1887, lured by the cheap and plentiful natural gas. The Kokomo Opalescent Glass Works started making stained glass in Kokomo in 1888 and has been in continuous operation ever since. "City of Firsts" As a result of the natural gas boom, Kokomo attracted an increasing number of industries, which resulted in significant technological innovations. For these industrial and technical achievements, Kokomo is officially known as the "City of Firsts." Among other achievements, Kokomo was a pioneer of the United States automobile manufacturing, with Elwood Haynes test-driving his early internal combustion engine auto there on July 4, 1894. Haynes and his associates built a number of other autos over the next few years; the Haynes-Apperson Automobile Company for mass-production of commercial autos was established in Kokomo in 1898. Haynes went on to invent Stainless Steel flatware in 1912 to give his wife tarnish-free dinnerware. In 1938, the Delco Radio Division of General Motors (now Aptiv) developed the first push button car radio. Kokomo serves as the "City of Firsts" in the food industry as well. In 1928 Walter Kemp, Kemp Brothers Canning Co. developed the first canned tomato juice because of a request
