Attack on the Latter-day Saint Chapel in Grand Blanc, Michigan

An non-denominational Evangelical Christian, who had a burglary conviction, two DUIs, and was a heavy meth user, who had a bad break-up with a Latter-day Saint woman years earlier in Park City, Utah drove his vehicle into an LDS Church in Michigan. He then entered, shot and killed two, shot and wounded eight others, doused the chapel with gasoline and burned it down. He was killed in a shoot-out with law enforcement. What motivated the shooter? Host Martin Tanner gives the likely sources.
