DAVENPORT, Iowa (AP) — Two Washington men have been sentenced to federal prison for conspiracy to manufacture methamphetamine.
Federal prosecutors say 58-year-old Timothy Kukowski and 50-year-old David Jay Butterbaugh had earlier pleaded guilty. They were sentenced on Wednesday.
U.S. Attorney Nicholas Klinefeldt says Kukowski will serve 10 years in prison and Butterbaugh, 17½ years. Both with serve several years of supervised release after their prison sentences end.
Klinefeldt says the two men agreed in late 2011 or early 2012 to manufacture meth at Butterbaugh's home in Washington.
Klinefeldt says their sentences reflect the fact that the judge found their operation created a substantial risk of harm to human life and the environment.
Meth labs contain hazardous chemicals that can be unstable and potentially explode.
