A man from Two Rivers will serve prison time for a repeat drunk driving conviction in Marinette County. 43-year-old Shannon Lee Dertz was sentenced to three years’ initial confinement and three years’ extended supervision Friday for OWI 5th or 6th. Dertz was allegedly caught driving while intoxicated in Crivitz in August of 2017 and the criminal complaint shows he blew a 0.15 in a preliminary breath test. A second, consecutive sentence of one-year initial confinement and one-year extended supervision was also imposed for Battery or Threat to a Law Enforcement Officer. In addition, Dertz will have his DOT driver’s license revoked for 36 months.
