A man indicted for the murder of his second wife and under investigation for the suspicious death of his first in 'glaringly similar' circumstances may have plotted to kill a third woman – his sister-in-law – according to newly submitted court documents. Harold Henthorn was indicted for the murder of his second wife, Toni, 50, last November. The indictment was the result of a two-year investigation during which the FBI eavesdropped on the Colorado widower's telephone conversations, combed through his finances, scrutinized his employment history and concluded that the 'freak' hiking accident that claimed the mother-of-one's life was murder. Dr Toni Jill Bertolet Henthorn plunged 140 feet to her death while on a remote hike with Henthorn who was the only witness to her death.

Harold Henthorn is being charged with the murder of his wife Toni who he claims fell to her death in Rocky Mountain Park

Toni had life insurance policies worth $4.5m and had almost died two years earlier when she was hit with a wooden beam while alone with her husband

Harold told different stories as to what happened at the time, and later joked 'I was trying to kill my wife'
@highlight
Court documents show he had a $250,000 life insurance on his sister-in-law and a 'romantic interest' in her

Court case will hear his first wife's death was in similar circumstances - although he has not been charged with her murder
@placeholder made payments on the policy until December 2012 and instead of listing her daughter as brothers as beneficiaries, the policy listed only Henthorn.
