{Winfield, West Virginia}...William Burt Shingleton, 45, of Poca, was sentenced Friday to 20 years in prison after being found guilty in June of 20 counts of possessing material visually portraying a minor engaged in sexually explicit conduct. Police seized Shingleton's computer in April 2010 after Shingleton's brother-in-law gave police a thumb drive, which his daughter had discovered contained pornographic images.
