IBERIA, Mo. (AP) — A Missouri woman has been charged in the poisoning death of her husband whose body was found after an arson fire at the couple’s home.

Miller County authorities announced Friday that 40-year-old Amy Murray, of Iberia, has been charged with first-degree murder and armed criminal action in the death of her husband, Joshua Murray. No attorney is listed for her in online court records. Bond is set at $750,000.
