The Pittsburgh medical researcher who sold country legend Tammy Wynette's medical records to the tabloids has been sentenced to six months in prison, the Associated Press reports. William A. Cox pleaded guilty in August to a federal charge of wire fraud for accessing the singer's confidential medical files. Cox sold them to The National Enquirer and The Star for $2,610. Wynette had been a patient at the University of Pittsburgh Medical Center Presbyterian Hospital in Pittsburgh in 1994 and 1995. Cox accessed her records by using a former doctor's password on the hospital computer system. Wynette died at her Nashville home in 1998, after years of health problems.
