WINONA, Minn. – A LaCrosse driver, who initially admitted to marijuana six hours earlier but denied any liquor, was arrested for drunken driving. The officer who made stop said that Madison Marie Eden, 20, changed her story as the roadside conversation continued. Told that a breathalyzer test showed her blood at 0.05% alcohol, she remembered sampling punch at a New Year’s party, the officer said. The stop was about 12:10 a.m. on U.S. Highway 61 on the East End near Bundy Boulevard. The officer said he could smell marijuana from the cabin of Eden’s car but didn’t sense alcohol. Eden failed walk-around field sobriety tests, however. The officer took this to mean that Eden’s erratic weaving, which had led the traffic stop, was due to the cumulative effect of marijuana and alcohol. The officer reported finding a  bowl with marijuana residue in Eden’s car. A blood sample for marijuana was taken and sent to the state crime lab.
