While feelings of shock still linger, an investigation is continuing into the apparent suicide this weekend of the man accused of killing Madison resident Joel Marino last year.
Adam Peterson, a former University of Wisconsin-Madison student and Minnesota native, apparently hanged himself. The Dodge Correctional Institution, which was holding Peterson, is investigating his death, including an apparent letter left by Peterson. Officials aren’t releasing any of the details surrounding that letter at this time, WISC-TV reported.
