Today, a federal jury convicted a Colorado man of murdering his wife by pushing her off of a cliff in the Colorado Rocky Mountain National Park. According to a report from the Associated Press, the two were on a wedding anniversary hike when the fall took lace, though the man initially claimed that the fall was an accident.

The jury found Harold Henthorn, 59, guilty of first-degree murder in only 10 hours. The deceased was Henthorn’s second wife, and was a prominent wealthy Mississippi native. She fell more than 130 feet off of a cliff in a secluded area to a jagged floor on September 29, 2012.

According to Henthorn’s initial account, his wife stopped to snap a photograph of the view and slipped over the edge. Defense attorney Craig Truman claimed that prosecutors failed to provide evidence that he was the one responsible for the fall.

Prosecutors alleged that Henthorn orchestrated the entire event, as he stood to collect almost $5 million in life insurance. Henthorn had a hard time keep his story straight, however, and the inconsistencies proved to be his downfall.

Harold Henthorn will be sentenced on December 8, and is facing a life term behind bars for the murder. Sandra Lynn Henthorn left behind a 10 year old daughter.
