A woman died after she fell while hiking in Rocky Mountain National Park, and police have indicted her husband in connection with her death, NBC News reported.
Authorities are also looking into the circumstances of his first wife's death in 1995.
Harold Henthorn, 58, was arrested on Thursday for the first-degree murder of his wife, Toni Henthorn, after she died while hiking on Sept. 29, 2012, according to the U.S. Attorney's Office for Colorado and parks officials.
Toni Henthorn fell roughly 50 feet from the side of the mountain around 6 p.m. Her husband's indictment said that he deliberately and maliciously premeditated the murder of his wife.
"When a violent crime such as this occurs in a national park, one of our nation's most treasured places, we work hard to ensure that those responsible are held accountable and the victim and the victim's family are afforded justice," Mark Magnuson, Rocky Mountain National Park Chief Ranger, said in a statement.
Harold Henthorn could face a mandatory life term in prison without the possibility of parole, as well as a $250,000 fine, if convicted, according to ABC News.
At the same time, police are trying to determine if Harold Henthorn was involved in the death of his first wife, Sandra, who was crushed after a car slipped off its jack in 1995. Douglas County sheriff's spokeswoman Deborah Sherman said the county has an active investigation going in the death of Sandra.
