Fox News has issued the following report on the search for Morgan Harrington, age 20, who went missing on October 17th during a METALLICA show at the John Paul Jones Arena in Charlottesville, VA:

Virginia State Police, acting on a reported sighting of a missing Virginia Tech student, shut down access to a motel in Charlottesville on Saturday, though the tip has yet to lead police to announce a break in the case.

The access road to the Comfort Inn at I-64 and Route 250 was blocked about 10 a.m. as state police followed up on a lead in the disappearance of Morgan Harrington. Harrington, 20, was last seen Oct. 17 outside a Metallica concert she'd attended with friends.

State police confirmed to Fox News that they were at the hilltop motel acting on a tip but said there was "nothing to it so far."

Police sources told CBS 19 that they were focusing on a parking lot in front of the motel after reports came in that Harrington had been spotted in the area.

Morgan's parents told Fox News that they believe their daughter was abducted.

"Each hour that passes is heavier than the hour before," Jill Harrington told Fox News' Geraldo Rivera.

Dr. Dan Harrington says a $100,000 reward is being offered for information leading to his daughter's whereabouts. Metallica has also offered a $50,000 reward.

Harrington vanished last Saturday night after getting separated from her friends at the concert at the University of Virginia in Charlottesville.

She left the John Paul Jones Arena to go to the bathroom, wound up outside somehow and wasn't allowed back in because of the venue's re-entry policy.

She phoned her friends about 9:30 p.m. that night to tell them she was leaving. No one has seen or heard from her since.

Meanwhile, the FBI has joined the search for Harrington.

Virginia State Police spokeswoman Corinne Geller said Friday the FBI will be able to investigate tips from around the country in the disappearance of the junior from Roanoke.

Montgomery County Sheriff Tommy Whitt says the task force investigating the killings of two Virginia Tech students in August checked for similarities with Harrington's case. He says they've found no connection between Harrington and the couple killed in the Jefferson National Forest.
