Scott White. Although Burnett was dead and Greene was ultimately acquitted of murder by claiming self-defense, the shooting tore his marriage apart. His wife never recovered from the loss of her daughter and died in Los Angeles in 1899 from ovarian-surgery complications. Greene married Mary Benedict (1876-1955) a few years later. Businessman On September 15, 1899, William founded the Greene Consolidated Copper Company to develop copper rich resources he discovered near Cananea. Greene Consolidated became in a very short time one of the richest sources of copper ore in the world, with an average output over 70 million pounds per year.

There was a call for help and Greene Consolidated was quickly supported by the local Sonoran Rurales and the Arizona Rangers, who entered Sonora against orders. In addition to the trouble with the miners, many of Greene's backers in New York began to turn on him. They began to sell their shares which
