A family member of several Union County fire victims says theyve been told the cause of a deadly fire on Saturday is electrical. A Kentucky State Police arson investigator spent the day at the Morganfield site. Police say Albert Tipitt and his four year old daughter, Caitlin, died of smoke inhalation. Two other children and their step-mom safely escaped the burning home. An eight year old boy was last listed in critical condition at a Louisville childrens hospital. His nine-year-old brother was in stable condition at Saint Marys Medical Center.
