Police are searching for a Virginia Tech student who hasn't been seen since she was separated from her friends at a Metallica concert Saturday.

Morgan Dana Harrington, 20, was last seen near the John Paul Jones Arena in Charlottesville, Va.

Her parents said they talk to her every day and her disappearance is very out of character.

"Morgan is a pretty transparent kid, who's had a really close relationship with us," her father, Dan Harrington, said in a phone interview Tuesday with the Associated Press. "I don't think there are lots of secrets, so this kind of behavior of (her) missing is not something I think we would expect."

Amy Melvin, her roommate in Blacksburg, Va. told The Roanoke Times Harrington went outside the stadium before Metallica went on stage, but she wasn't sure why.

"Everyone assumed she'd be coming back, " Amanda Melvin, Amy Melvin's older sister told the newspaper. "Sitting here while Morgan is out there missing isn't a very good feeling,"

Harrington drove to the concert and her car was still in parking lot after, the newspaper reported.

Her cell phone and purse were found outside the arena.

Harrington's father, who lives in Roanoke, said his daughter had asked him to help her study for a math test and go through the class schedule for next semester on Sunday. He called her friends around 12:30 p.m. when he realized he had not heard from her.

Dan Harrington told Fox News this not typical behavior for his daughter.

"Morgan is pretty close to us as a family," he said, adidng his daughter didn't have a boyfriend and didn't know if anyone who would want to hurt her. "We don't think she is out there with someone she choose to be with."

Police said Morgan Harrington, a junior majoring in education, was wearing a black T-shirt with "Pantera" across the front in tan letters, a black mini skirt, black tights and black knee-high boots.

She has long blonde hair and blue eyes, is 5-foot-6 and weighs about 120 pounds. She was not carrying an identification card or cell phone.

Investigators are treating the disappearance as a missing person case, said Virginia State Police Lt. Joe Rader.

"We have no evidence that a crime has been committed," he said.
