AlHijjah 08, 1436, September 22, 2015, SPA -- A federal jury has convicted a man of murder in the death of his wife, who fell off a cliff as they hiked in Colorado's Rocky Mountain National Park to celebrate their wedding anniversary, according to AP. Jurors on Monday found 59-year-old Harold Henthorn guilty of first-degree murder in the death of Toni Henthorn. Defense attorneys argued that she accidentally fell while snapping a photo and prosecutors' evidence was largely circumstantial. Prosecutors argued during a two-week trial that Henthorn staged his wife's death to look like an accident because he stood to benefit from her $4.7 million in life insurance policies. They said Henthorn gave inconsistent accounts of the deadly hike and could not explain why he had a park map with an "X'' drawn at the spot where she fell.
