A former Albia High School soccer coach has been charged with sexual abuse of a minor.  The Iowa Department of Public Safety says 36-year-old Aaron Koester was arrested last Friday in Indianapolis, Indiana and extradited to Monroe County.  Koester is charged with two counts of second degree sexual abuse and two counts of third degree sexual abuse.  The Department of Public Safety says these charges are not the result of interactions Koester had as a coach.  Koester is being held on $200,000 bond in the Monroe County Jail.
