A former Louisiana Board of Cosmetology official admitted in Baton Rouge federal court Thursday that he sold answers to board-administered cosmetology exams for cash.

Winn Johnson, 71, of Boyce, in Rapides Parish, pleaded guilty to using the telephone in aid of bribery.

U.S. Attorney Walt Green said the ongoing probe is being handled jointly by the FBI and Louisiana Inspector General’s Office.

Those agencies began investigating Johnson and others in 2013 after receiving allegations that Johnson would accept cash from people who were scheduled to take cosmetology board exams, Green said.

Johnson admitted in court Thursday that, on three separate occasions, he met with a person whose wife Johnson believed was seeking to obtain a cosmetology license. Each time, Johnson gave the person answers to an upcoming board exam in exchange for $500 in cash.

Johnson used his cellphone to arrange the meetings on various dates last year in Baton Rouge.

Chief U.S. District Judge Brian Jackson did not set a sentencing date for Johnson.

Green said the cosmetology board has been cooperating with the probe.
