Amy Murray, 40, has been released after posting $750,000 bond following her arrest last week on first-degree murder, second-degree arson, tampering with physical evidence and armed criminal action charges, according to Miller County jail records. PEOPLE was unable to reach her for comment. It was unclear Monday if she had entered pleas to the charges or had retained a lawyer who could speak on her behalf. The Miller County Sheriff’s Office alleges in a probable cause statement that Murray used an accelerant to start the December 11 fire at the Iberia, Missouri, home she shared with her husband. Fire marshals determined the fire was intentionally set. According to the statement, an autopsy showed Joshua Murray, 37, was dead before the fire started. Murray allegedly placed her husband’s lifeless body on their bed and started the fire before leaving with her dogs and child, according to the statement. Murray then allegedly drove to a McDonalds, returning a short while later to find the house fully engulfed. She called 911 and fire crews responded to extinguish the fire. Police were suspicious of Murray’s alleged account that she returned to find the house on fire and that the smoke was too intense for her to try to save her husband, according to the statement. Detectives investigating the fire would learn Murray was employed as a nurse at the Jefferson City Correctional Center in Jefferson City, Missouri. Police discovered evidence that Murray had allegedly become romantically involved with an inmate: In phone conversations recorded by the prison, Murray allegedly said she wanted to marry the inmate, according to the statement. “During the phone calls, Amy Murray talks about not wanting to be around her husband, Joshua Murray, and was wanting a divorce from him,” the statement reads. She even allegedly told the inmate — 40-year-old Eugene Claypool — in one call the two could now get married because her husband was dead. • Want to keep up with the latest crime coverage?
