(WXYZ) -- The desperate search for an Ohio woman may be crossing the border into Michigan.
Sierah Joughin was last seen Tuesday evening just before 7 p.m.
She had just finished a bike ride with her boyfriend when the two parted ways, but she never made it home, according to authorities.
The Fulton County Sheriff's Office in Ohio is treating this case as an abduction.
Michigan State troopers are involved because it happened near the border and the suspect vehicle reportedly had Michigan plates.
