Murder charge added in teen's shooting death on Fond du Lac Reservation The additional charge significantly increases the potential sentence Joseph Fohrenkam could face if convicted of killing 16-year-old Joseph Peterson. 3:40 pm, Mar. 4, 2021 × Joseph James Fohrenkam Prosecutors have added a third-degree murder charge against the Brevator Township man accused of fatally shooting his friend in late December. Joseph James Fohrenkam, 18, already was facing a felony count of second-degree manslaughter in the death of Joseph James Peterson, 16. But he now faces a significantly stiffer sentence if convicted of murder. Authorities said Fohrenkam was "showing off" his pistol when he discharged it, apparently by accident, while drinking with Peterson and three other friends in a car on the Fond du Lac Reservation. Fohrenkam and his mother allegedly went on the run before they were arrested more than a week later in northwestern Minnesota.
