Bossier Parish Sheriff's Detectives have arrested a Haughton man for allegedly engaging in inappropriate sexual behavior with a juvenile family member and for having hundreds of videos of child pornography.  Detectives say 69-year-old James Bonacci was arrested after a teenaged relative told them that he had engaged in sex with her several times when she was between the ages of 5 and 7 and that he had taken nude photos of her.  They say he's admitted to them that he had about 1,000 videos of child pornography on his computer but they say he's denied raping the girl.  After interviewing him, detectives obtained a search warrant for Bonacci's Haughton home where they seized computer equipment and cameras.  They're investigating now to determine if additional charges should be filed.  He's been booked into Bossier Max on charges of aggravated incest, aggravated rape, and pornography involving a juvenile and is being held in lieu of $780,000 bond.
