Andrew Thomas Jondle, 20, and his girlfriend, Cindy Lou Beck, 47, remain in the Polk County jail. They're accused of murdering Jondle's parents, Marilyn and David Scott Jondle, on Aug. 31.
Andrew Jondle was arraigned on an indictment charging him with burglary and two counts each of aggravated murder, murder and robbery. He pleaded not guilty to the charges, according to court officials.
Beck, whose birthday was Friday, also pleaded not guilty, her attorney Chris Burris said. She faces two counts each of aggravated murder and conspiracy to commit aggravated murder.
Officials think Andrew Jondle and Beck planned to rob the Dallas couple in order to pay the rent on their South Salem apartment
. Investigators found David and Marilyn Jondle's credit cards at that apartment, according to a probable-cause statement. The statement provides legal ground for an arrest.
David Scott Jondle, 61, and Marilyn Jondle, 58, owned Abundant Life Farm. The farm produced poultry, eggs, pork, beef and lamb without antibiotics or hormones.
