One of the most bizarre, complex and ultimately tragic criminal cases in Utah history is now the subject of a Netflix documentary.
On Oct. 15, 1985, Hofmann killed two prominent Utahns with homemade bombs in a desperate attempt to thwart the discovery of his fabrications.
Following these bombings, police investigations revealed Hofmann had forged a number of historical documents, including a previously unknown Emily Dickinson poem, Founding Fathers' signatures and — most famously — the Salamander Letter, which presented a narrative of Joseph Smith’s discovery of the gold plates that countered The Church of Jesus Christ of Latter-day Saints' account, including Smith's description of an angel that appeared to him as a white salamander.
With information gathered from the Deseret News archives, here's a look back at the strange events that preceded and followed the tragic murders.

1980–Oct. 1985: Hofmann makes his living through forgery, selling many purported documents to The Church of Jesus Christ of Latter-day Saints.
