The Vigilantes of Montana:
1864 Revisited

Victim 1: George Brown

George Brown was 26 when executed by the vigilantes. His "crime:" He had written a letter to Alex Carter warning him that a lynch party was after him.

At age 23 George Brown married an Indian girl in New Ulm, Minnesota, then on the frontier of settlement. In late 1862 he left his wife and family to seek fortune in the new gold fields in the west, but he became instead a ranch hand, and bartender at Dempsey's station on the Bannack - Virginia City stage road. Why he wrote the letter warning Alex Carter we will never know, but that in itself was no crime. To the end he did not confess, but was hanged anyway.

My opinion:

There is no evidence that he was guilty of any crime.
