Knee-deep mud and challenging geography were hampering rescue teams Wednesday as they searched for six people who disappeared during a flash flood that killed three in the state of Kentucky. Johnson County Coroner J.R. Frisby confirmed that a third body was found Wednesday afternoon in the same general region of the two other bodies uncovered Tuesday. Crews were combing the wooded, mountainous terrain, hampered by swarming mosquitoes, soupy humidity and mud. Rescue teams were going door-to-door to try to find the missing as desperate families waited for word, AP reported. Kentucky Governor Steve Beshear declared a state of emergency after the Monday afternoon flood, giving local officials immediate access to state resources to assist in recovery efforts. Seven cadaver dogs were aiding in the search, which stretched more than 8 rugged miles (13 kilometers) - an area with 500 homes and 1,200 residents about 120 miles (190 kilometers) east of Lexington, the state's second largest city, police said at a news conference. Authorities estimate more than 150 homes were destroyed.
