TOLEDO, Ohio (AP) – The FBI has joined the search for a university student whose purple bicycle was found abandoned in an Ohio cornfield.

The Blade in Toledo reports that 20-year-old Sierah Joughin was last seen riding the bike around 6:30 p.m. Tuesday in the Metamora area of Fulton County. County Sheriff Roy Miller says the bike was found in the field off a county road around midnight that night, about an hour after Joughin’s mother filed a missing-person’s report.

Joughin is from Metamora and is a student at the University of Toledo.

Authorities say the corn around the bike had been trampled.

The FBI’s Toledo supervisor confirmed his office is working with other law enforcement agencies. No suspects have been named.

A $25,000 reward is now being offered to anyone who may have information that leads to her being found.

Joughin is described as a white female, 5’5″ tall and weighing about 130 lbs. She has brown eyes and mid-length, brown hair. She was last seen wearing shorts, a neon yellow tank top, and tennis shoes.
