Carlos Wilson sexually molested the girl on a number of occasions over a two-year period beginning when she was 11 years old.
Wilson's DNA sample obtained when he was arrested in this case led to his indictment Tuesday on rape and burglary charges in an unrelated case.
In the case for which he was sentenced, Wilson had been dating the girl’s mother for six years, but she notified police in 2011 when she found a phone video of him fondling her daughter’s bare bottom.
The videos were discovered when Wilson lost his phone in Miami and it was returned to the victim’s mother.
Criminal Court Judge John Campbell sentenced Wilson on Monday to 12 years in prison for aggravated sexual battery and to nine years in prison for especially aggravated sexual exploitation of a child.
The sentences must be served consecutively and without parole.
Meanwhile, Wilson’s DNA sample taken after his arrest linked him to an unsolved burglary and rape in 2010 in the Raleigh area.
The assailant raped a woman there on Jan. 29, 2010, and stole a digital camera. DNA evidence was preserved in the Combined DNA Index System (CODIS).
After Wilson’s arrest for molesting his girlfriend’s young daughter, a DNA sample taken from him matched the unknown sample preserved from the 2010 rape of the Raleigh woman.
On Tuesday a Shelby County Grand Jury indicted him on charges of rape and aggravated burglary.
The case was handled by assistant district attorney Abby Wallace of the District Attorney's Special Victims Unit (SVU).
The unit prosecutes cases of child sexual abuse and severe physical abuse of child victims; rape and aggravated rape of adult victims, and abuse of elderly and vulnerable adults.
SVU reviews child-victim cases cooperatively with Shelby County's multi-agency Child Protection Investigative Team.
