ST. PAUL — State Rep. David Dill, who represented northeastern Minnesota and focused much of his legislative efforts on mining, outdoor recreation, the environment and natural resources, died after a short battle with cancer. He was 60.

Dill, DFL-Crane Lake, died Saturday night after getting the diagnosis only a month ago, said Senate Majority Leader Tom Bakk. Bakk, who said he received word of Dill’s death from his wife and son, said Dill’s organs ultimately shut down from the chemotherapy treatments.

“He was as hard of working member of the state house as I’ve ever seen,” Bakk said Sunday of his friend. “He always put his constituents first.”

Dill represented Koochiching, northern St. Louis, Lake and Cook counties, since 2002. He was re-elected in November with more than 65 percent of the vote in a district that is the largest in the state by area. Dill, chairman of the Lands Subcommittee, also worked on agriculture finance and economic development issues.

Gov. Mark Dayton released a statement Sunday, saying he would miss Dill. “David was deeply committed to Minnesota. As a legislator, he advocated tirelessly for the best interests of his district and the general welfare our state.”
