Massachusetts boy's rap videos spark child abuse investigation Massachusetts authorities say they have lodged child abuse and neglect complaints against a man whose 9-year-old son appears in sexually suggestive rap videos posted online. Police in Brockton said Sunday they are also informing state child welfare officials about the videos that feature fourth-grader Luie Rivera Jr., who goes by the stage name Lil Poopy. The videos show the boy slapping a woman's buttocks, engaging in sexually suggestive dances and glorifying drug use and materialism. Lt. David Dickinson told The Enterprise that the videos are "a bit much for a 9-year old." Police started investigating after a feature story on the boy appeared in the paper. His father, Luis Rivera, said his son is simply acting and not doing anything wrong. He said he plans to contact his lawyer.
