Stanton "Nan Nan" Guillory, a federal inmate who was housed at the St. Tammany Parish Jail, was found guilty on three counts of obscenity for exposing himself and masturbating in from of female employees.
He will be sentenced 22nd Judicial District Judge Raymond Childress on Feb. 22.
Guillory is facing federal charges in an alleged 2012 murder-for-hire scheme that resulted in the death of Milton Womack, a guitarist who was a witness in the federal Medicare fraud case against Louis Age Jr.
Authorities say that Age, his son and three others conspired to kill Womack to prevent him from testifying. Guillory allegedly killed Womack in expectation of payment.
He also was charged as the driver in the 2012 shooting of 5-year-old Briana Allen and Shawanna Pierce in Central City.
The obscenity charges arose from three separate occasions last year when Guillory exposed himself and masturbated in front of female jail workers, despite that the DA's office described as "multiple warnings" for him to stop.
