U.S. District Judge Dale Kimball imposed the minimum sentence Wednesday for 21-year-old Joshua Raymond Townsend of West Jordan.
Court records show Townsend warned police of his plans in an early-morning 911 call Nov. 17, 2011. The first Molotov cocktail failed to ignite. The second hit the bank, broke a window and started a bush on fire. Townsend tried to add gasoline but the fire went out by itself and he was arrested a short time later.
Authorities say Townsend ordered five pounds of explosive chemicals to blow up the bank months earlier but decided to use Molotov cocktails instead.
He pleaded guilty in April to arson.
