Newcomb started working with the Dalton Gang subsequent to meeting Doolin, participating in a messed up prepare theft in Adair, Oklahoma in July 1892 that brought about both being booted from the posse. Doolin took this as his signal to frame The Wild Bunch in 1893, of which Newcomb was an establishing part. By 1895, Newcomb was one of the United States' most-needed men and had an abundance of $5,000 on his head.
