A statewide Green Alert has been issued in Kentucky for a missing 70-year-old Boone County man, William D. Singleton, who deputies say may be armed and whose family fears he could be suicidal. Singleton, a Vietnam veteran diagnosed with PTSD, Parkinson's, and dementia, was last seen on April 6 at his residence in Burlington and is believed to be traveling in a 1989 Chevrolet RV-style vehicle.
