An Oskaloosa man is accused of sharing x-rated pictures of teenage girls on social media.  Albia Police and the Division of Criminal Investigation arrested 30-year-old Andrew James Richardson last week. Albia Police were told that sexually explicit photos of a juvenile girl were sent to a social media user who claimed to be 16 years old.  An investigation found Richardson owns the social media account.  As law enforcement investigated further, they turned up more sexually explicit photos of teen girls…as well as evidence of sexual contact between Richardson and a juvenile girl.  Richardson is charged with two counts of third degree sexual abuse, three counts of enticing a minor and four counts of sexual exploitation of a minor.  Richardson is being held in the Monroe County Jail on $75,000 cash only bond.
