Paducah, KY – A suspect in a nearly 3-year-old murder investigation won't be getting out of jail any time soon. Kentucky Parole Board members denied Penny Baird Shemwell's request during a hearing today. She has served three of her fifteen year sentence on shoplifting and gun charges. Shemwell's past may have been a factor in the decision. She has two previous felony theft convictions and is the focus of a police investigation into her husband's 2006 death. Dr. Frank Shemwell's body was found in his home after a fire. An autopsy concluded he died from blunt force trauma and smoke inhalation. Shemwell can seek probation again in 24 months.
