An Ohio teenager who disappeared more than three weeks ago has been found alive by police, Fox8.com reported.

Abigail "Abbi" Obermiller, 17, of Huron County, Ohio, had last been seen around midnight on June 7 inside her grandmother's home, approximately 10 miles from her parents' residence in Norwalk.

Abbi's father, Jim Obermiller, said it was an anonymous tip that led police to Abbi, Fox8.com reported.  She reportedly had been staying in an apartment that was rented by her boyfriend, 20-year-old Robert "Bobby" Young, three weeks ago in New London, Ohio.  

Abbi's parents told Fox8.com that they have spoken to Abbi since she was found but have yet to be reunited.

Young was arrested and charged with obstruction of justice in the case. He had claimed not to have any knowledge about Abbi's disappearance, Fox8.com reported.

"I don't know where she is. I have no idea where to start," he reportedly told Fox 8.

In an interview with FoxNews.com on Sunday, Abbi's mother, Rose Obermiller, had expressed her concerns about Abbi's boyfriend. Obermiller said Young was "very possessive" and "controlling." 

Rose Obermiller said that both she and her husband, James, disapproved of Young, who they say became increasingly possessive over their daughter since the couple began dating last August. 

"She was upset because we didn't like her boyfriend," Overmiller said.

Police allege that Young sent Abbi a string of text messages prior to her disappearance that implicated his involvement in the case. 

Young has pleaded not guilty in the case and is reportedly scheduled to appear in court on July 7.
