He was part of a significant number of Utah Latter Day Saints going to study law at the University of Michigan in this time period.
He was arrested for unlawful cohabitation in 1889, but left on a mission for The Church of Jesus Christ of Latter-day Saints to England before he was prosecuted.
[1] Thurman also "eloquently pleaded for reducing the twelve-person jury as an economy measure that would not jeopardize justice for the accused".
