Joseph MacDonald (1856-1939) was a wealthy mining engineer and executive. He worked at the Avalon Smelter in British Columbia, and then in various mines in Gem, Idaho; Juneau, Alaska and Mexico.

On 14 May 1902, while he was managing the Treadwell Mines in Juneau, Alaska, MacDonald shot and killed religious fanatic N.C. Jones because Jones, a missionary, believed God had instructed him to make sure the sabbath was observed. The operations at Treadwell, the largest gold mine in existence when in operation, only closed down for Christmas and Independence Day. Jones and MacDonald had already had confrontations about closing on Sundays and efforts were being made to keep Jones away. However, when MacDonald returned home, he was confronted by Jones who was armed and tried to shoot him. MacDonald fired and hit Jones in each arm and twice in the torso which led to his deathOne version. The Mexican Herald reported that “It had been charged that McDonald brained the missionary with a crow-bar.”.

MacDonald was originally cleared of wrong doing and continued to run the mine. Then, in early 1907 he took over from his brother, M. E. MacDonald, as general manager of the Guanajuato Consolidated Mining and Milling company.

In December 1912, while still general manager, MacDonald was indicted for Jones' murder, ultimately extradited to the United States, tried and on 1 August 1913 found not guiltyThe Mexican Herald, 18th Year, No. 6,545, 2 August 1913.

The local newspaper, El Observador, said that it realized that they were not of forced circulation, but they had been issued with the approval of businesses and the public and did state that the companies would redeem them with legal tender as soon as business communications were restored with the capital of the Republic. The paper was aware of poor people who had not been able to buy necessities, and speculators who were buying the notes at less than face value.
