A nineteen-year-old Summerville man has been arrested and charged with child molestation.  Logan Jayden Pickern was arrested on Thursday morning of last week after an investigation by the Chattooga County Sheriff’s Office.  Sheriff Mark Schrader told WZQZ News over the weekend that Pickern was carrying on a sexual relationship with a twelve-year-old female child.  Pickern was arrested last week by Investigator Daniel Sanford after an investigation that began last month and concluded that Pickern was having sex with the child.  Pickern was booked into the Chattooga County Jail and was subsequently released on a $50,000 bond, according to Sheriff Schrader.
