An East Texas man has been arrested for the chainsaw murder and dismemberment of his business partner and friend of 20 years. Authorities charged 43-year-old Christopher Lee Takhvar, of Jefferson, with second-degree murder in the death of 62-year-old Robin Lee Upson, of Florida. Takhvar told Florida detectives that the killing was accidental and he didn’t mean to turn on the chainsaw. He was arrested in Marshall and will be extradited to Florida.
