NEW CHARGES: Jail nurse poisoned husband, wanted to wed inmate
KANSAS CITY (CNN) — A Missouri jail nurse who allegedly wanted to marry a man convicted of killing a lottery winner has new charges in the poisoning death of her husband.
Amy Murray has been charged with first-degree murder and armed criminal action in the Dec. 11 death of Joshua Murray, whose body was found in the master bedroom of the couple's burned-out home in Iberia.
Court documents said Murray used antifreeze to kill her husband and then set their home on fire to try and cover up the crime.
Investigators said Amy Murray later told the prison inmate in a recorded phone call that they could get married because her husband was "out of the picture."
Murray has also been charged with second-degree arson and tampering with physical evidence.
Murray reported finding the home on fire when she returned from taking the couple's 11-year-old son and two dogs to a McDonald's, a Miller County sheriff's detective wrote in a probable cause statement released last week. She told investigators she couldn't get inside the home because the house was filled with smoke.
But investigators said they found a McDonald's sandwich on the kitchen counter at the house.
Murray worked part-time as a nurse at the Jefferson City Correctional Facility, where she had a "romantic relationship" with inmate Eugene Claypool that had been ongoing "for some time," according court documents.
Claypool, who isn't charged in the case, was sentenced to life in prison for fatal stabbing an elderly man in 2000.
Claypool and another man pleaded guilty to killing 72-year-old Donald Hardwick, who was attacked in his home on Christmas Day in 2000. Hardwick, who couldn't walk without using a walker, won a $1.7 million Missouri Lottery jackpot in 1998.
Investigators said Claypool and his co-defendant targeted Hardwick believing he had $10,000 stashed in his Springfield home and Claypool repeatedly stabbed Hardwick, whose wife later found him dead with a Bible on his chest.
