Abigail Obermiller who goes by "Abbi" was last seen midnight Sunday, June 6, in North Fairfield, Ohio.

The 17-year-old is believed to be in danger because she went missing while she was with her 20-year-old boyfriend Robert J. "Bobby" Young, reports The Norwalk Reflector.

Police have Young in custody; however, Young is refusing to provide any information regarding Obermiller's whereabouts, and has been arrested and charged with obstructing official business, says the newspaper.

Young, who posted bail and was released, agreed to take a polygraph test, but decided to back out after consulting a lawyer.

Police Chief Dave Light told the Sandusky Register, "We're trying to rule out foul play, and at this point we can't."

Authorities told WRC-TV that the couple was planning to go to West Virginia and get married, but Obermiller's family believes they never made it there, and that she is being held against her will by her boyfriend's family in  Detroit or Toledo.

"It's not like her to do this," her father Jim Obermiller told The Norwalk Reflector. "Not calling ... I'm not understanding that. At least call and let us know she's safe."

Abigail is 5'10" and weighs 120 pounds. She has blue eyes and long, curly brown hair. The 17-year-old also has a mole in the center of her chest and often wears a gold necklace with an "A" and a small string of diamonds, says WRC.

Anyone with information on her whereabouts should contact Norwalk, Ohio police at 419-663-6780.
