Another person of interest in the case of a missing teenager has been arrested. The Portage County Sheriff’s Office says 34 year old Elliot Adams was taken into custody Monday afternoon on a warrant issued by the state Department of Corrections. According to Chief Deputy Dan Kontos, 16 year old Rayna Griffin is still missing. Griffin went missing Saturday after leaving a group home in Stevens Point with another man, 21 year old Terry Warren. He was arrested later Saturday on a probation warrant. Authorities think Griffin is still in the central Wisconsin area, and continue to ask the public for help in locating her.
