GRAND RAPIDS, Mich. (AP) - Don Davis is retiring after 40 years as a federal prosecutor in western Michigan.
Davis is a well-known lawyer in Grand Rapids. He's spent his career at the U.S. Attorney's Office there and served as head of the office for four years before President Barack Obama finally got a nominee approved by the U.S. Senate in 2012.
MLive.com says Davis disclosed his retirement in a letter to colleagues Friday.
Davis has handled many high-profile cases. He was one of two prosecutors in the 2002 trial of Marvin Gabrion, who was convicted of killing a woman in a national forest and now is on federal Death Row.
Davis regularly prosecuted tax rebels in western Michigan who claimed tax laws didn't apply to them.
