Roden, was hidden in a freezer in a garage at his house. After he telephoned police, Rothstein wrote a suicide note indicating his planned death had nothing to do with Wells. Investigators do not believe Rothstein ever attempted suicide. Roden had been living with Diehl-Armstrong for 10 years. In custody, Rothstein claimed Diehl-Armstrong had murdered her then-boyfriend Roden with a 12-gauge shotgun during a dispute over money. Rothstein said she subsequently paid him $2,000 to help hide the body and clean the crime scene at her house. In January 2005, Diehl-Armstrong pleaded guilty but mentally ill to third degree murder and abuse of a corpse for killing Roden and was sentenced to between seven and twenty years in prison. She is believed to have killed Roden to prevent him from informing authorities about the robbery plot. Diehl-Armstrong and Barnes charged In April 2005, Diehl-Armstrong told a state trooper she had information about the Wells case and after meeting with FBI agents, said she would tell them everything she knew if she was transferred from the Muncy Correctional Institution to a minimum-security prison in Cambridge Springs. During a series of interviews, Diehl-Armstrong admitted to providing the kitchen timers used for the bomb, stated Rothstein masterminded the plot and that Wells had been directly involved in the plan. In late 2005, Barnes, who was in jail on unrelated drug charges, was turned in by his brother-in-law after revealing details of the crime to him. On September 3, 2008, Barnes pleaded guilty to conspiring to rob a bank and to aiding and abetting. On December 3 that year, he was sentenced to 45 years in prison by a federal judge in Erie for his role in the crime. Barnes's sentence was later reduced to 22.5 years after he testified against Diehl-Armstrong. In July 2007, U.S. Attorney Mary Beth Buchanan announced Diehl-Armstrong and Barnes had been charged with the crime, with Diehl-Armstrong as the mastermind. The deceased Rothstein and Wells were named as un-indicted co-conspirators. Buchanan stated Wells had been involved in the plot from the beginning but that his co-conspirators fitted him with a real bomb that would have exploded even if it were removed. Diehl-Armstrong trial On July 29, 2008, U.S. District Court Judge Sean J. McLaughlin made an initial finding that Diehl-Armstrong was mentally incompetent to stand trial due to a number of mental disorders, indicating this ruling would be reviewed
