Berit Beck

Fond Du Lac, Wisconsin · 1990

Berit Beck, an 18-year-old from Sturtevant, Wisconsin, vanished on July 17, 1990, while driving to a computer seminar in Appleton. Her van was found abandoned two days later in a Kmart parking lot in Fond du Lac, and her body was discovered about a month afterward in a ditch near Waupun; she had been suffocated and strangled. The case stayed cold for nearly 25 years until a 2014 re-analysis of evidence from the van matched fingerprints to Dennis Brantner, a Kenosha trucker. After a 2016 trial ended in a hung jury, Brantner entered an Alford plea in 2018 to second-degree reckless homicide and was sentenced to 10 years in prison.
