ST. THOMAS — U.S. Attorney Gretchen Shappert is asking a judge to evict the son of sailmaker Manfred Dittrich from Hassel Island, arguing that his late father’s permission to occupy a parcel in the National Park is non-transferable, according to documents filed in U.S. District Court.

Manfred Dittrich, 80, one of the last remaining residents of Hassel Island, died in June 2016 after living and working there for decades.
