Two former employees at a Waterloo convenience store have been convicted of selling a cold medication for the purpose of making methamphetamine. The U.S. Attorney’s office says this is the first case of its kind in the area where the people who supplied the makings for the meth were not actually involved in manufacture of the drug. 34-year-old David Mikelson, formally of Waterloo, and 26-year-old Paul Finn of Waterloo, were convicted of conspiracy to manufacture meth and conspiracy to distribute psuedophedrine intending or expecting it to be used in manufacturing meth. Mikelson was the manager of a Waterloo convenience store and Finn was an employee when they allegedly sold cases of the cold medication psuedophedrine to several people involved in cooking meth. Mikelson faces 10 years to life in prison and four million dollars in fines. Finn could get five to 40 years in prison and up to two million dollars in fines. A sentencing date has not been set.
