A young Ohio woman has disappeared without a trace near the Ohio State University campus in Columbus, according to the Ohio News Network.

Julie Popovich (search), 20, of neighboring Reynoldsburg, disappeared more than ten days ago from an off-campus bar she had visited with friends, the network said.

She was last seen at about 1 a.m. on August 11th outside Ledo's Bar (search) on North High Street near the university, getting into a car with a man her friends did not recognize.

According to the police report, her friends said they thought she knew the man. "She was at the bar with co-workers and friends, they did not get a good look at him. It did appear she left willingly," Sherry Mercurio of the Columbus Police Department told FOX News.

"She is not the type of person to just up and disappear and drop off the face of the earth. She is a responsible girl. she was close with her family," Mercurio added.

Popovich is a part-time model and student and works at a Max and Erma's (search) restaurant in Reynoldsburg, according to local newspaper The Newark Advocate.

She was described as having brown hair and brown eyes, standing 5 feet 10 inches tall and weighing 110 pounds.

"We look at these situations in three levels: she could be gone voluntarily and not want to deal with her family or whatever; she could be gone involuntarily such as being injured or in an accident and unable to call; or there could be foul play. So far nothing has come up to suggest foul play," Mercurio said.

Popovich's family and friends have distributed hundreds of fliers in her neighborhood in hope that someone will come forward. Her family has offered a $5,000 reward for information leading to her return, according to WMCH-TV of Columbus.

"That's what we've got to do," Popovich's aunt, Dena Honeycut, told the TV station. "Talk to God, say our prayers, [hope that] she's going to come home safely."

The Advocate reported that Crimestoppers had received only a handful of tips on the case.

"She had a number of events coming up that she was looking forward to attending. Those events have come and gone," Mercurio said.

Area residents urge anyone with information to make an anonymous call to Crime Stoppers at (614) 645-TIPS.
