{Charleston, West Virginia}...FBI agents said Monday they arrested 78 year old Jack Edwin Gravenmier of Charleston over the weekend at a motel in St. Louis, Missouri on charges of traveling across state lines with plans to sexually abuse a child. The FBI says Gravemier sexually abused a 14 year old male in Georgia last summer and had planned to attempt another assault in St. Louis. Agents say Gravenmier sent four sexually explicit images to the victim and told the boy that he'd had sex with a boy in one of the photos.
