A 15-year-old accused of murdering New Orleans tour guide Kristie Thibodeaux was wearing a deactivated court-ordered ankle monitor at the time of her killing, sources told Fox 8.  Kevin Nunez is accused of firing the fatal shot on June 30 as Thibodeaux sat in her car on St. Peter Street.  According to court documents, Nunez was released from custody and sentenced to home incarceration by Chief Juvenile Court Judge Candice Bates-Anderson after being found guilty in juvenile court of seven counts of aggravated assault, illegal possession of a handgun and domestic battery abuse. On May 21, an arrest warrant was issued after Nunez allegedly failed to adhere to the conditions of his release.
