In March 1873, two Norwegian-born women who lived on the desolate Smuttynose Island, one of the Isles of Shoals off the coast of Maine and New Hampshire, were brutally murdered. Maren Hontvedt, a sister of one of the victims, survived by hiding in a sea cave until dawn. The murdered women were her older sister Karen Christensen and Anethe Christensen, their sister-in-law. A man named Louis Wagner was tried and hanged for their murders, mostly on circumstantial evidence. His conviction has been argued about, as some people think he could not have done it.
