William Collins was an associate of Sam Bass, and a member of the Joel Collins (his brother) Gang (photo) that held up a Nebraska train of $60,000 in 1877. William Collins then hid out in Pembina, Dakota Territory. But Deputy US Marshal William Anderson tracked him down.
On November 8, 1878, the two got into a gunfight at the local post office. Both died. There was an irony. The two had grown up together; each had served as best man in the other’s wedding. Anderson’s widow collected the $10,000 reward on Collins.
