Almost three days after a 20-year-old Virginia Tech student from Roanoke went missing at the John Paul Jones Arena in Charlottesville, Virginia State Police and University of Virginia Police continue to look for her.

Investigators say they are following up on a couple dozen new leads that have come in since Monday's press conference with Morgan Dana Harrington's parents.

Police activity and searches will continue Tuesday near the JPJ. State and UVA police have been canvassing the area since Monday to make sure nothing is out of the ordinary, and that no additional evidence was overlooked.

On Tuesday, police did find a black cloth and took it into evidence. However, there is no word at this time about what that cloth was.

Police investigators say they've received calls regarding Harrington's disappearance, and are following up on them Tuesday. Each tip is prioritized based on the information provided.

Police are still encouraging the public to come forward with any information, especially those who may have gone to the Metallica concert Saturday night.

Anyone who may have been recording or taking pictures of the concert and/or audience with a camera or a cell phone Saturday night is asked to look over the video and pictures for someone who might resemble Harrington and contact police.

Harrington was last seen around 8:40 p.m. Saturday. She had gone inside JPJ with a group of friends, but ended up getting separated from them during the concert.

If you have information you would like to report, can can call Virginia State Police at434-352-3435 or e-mail bci-appomattox@vsp.virginia.gov.

UVA Police can be reached at 434-924-7166.

Harrinston's family is speaking out, asking the public for help in finding her.

Holding back tears, Harrington's parents are hopeful that their daughter will come home safe.

"Please come home. If someone has Morgan, please let her come home safely," says Dan Harrington, Morgan's father.

Harrington traveled to Charlottesville with a group of friends to see the popular metal band Metallica. She met up with a group at James Madison University, and they all made it to the John Paul Jones Arena safely before being separated.

Morgan's father reported her missing at 12:30 p.m. Sunday. She was supposed to be back home to take an exam for which she had been studying. Morgan's father said it was uncharacteristic of her not to call.

Police say if Harrington is found, she probably won't have any identification or cell phone on her. They would not specify why, but ABC13 in Lynchburg reports that the Harrington's family pastor says Harrington's purse was found in the parking lot of the JPJ Arena.

"That's our biggest concern. It's unusual that her friends and family haven't heard anything regarding her whereabouts. That's the biggest concern, is her whereabouts and her welfare," says Lt. Joe Rader from the Virginia State Police.

The search is a missing persons investigation, which means police believe there's still a chance she's alive. Search helicopters and canines have been heavily searching the UVA area in the hope of finding some clues about what happened to her in Charlottesville.

Throughout this difficult and heart wrenching ordeal, Harrington's mom is staying hopeful.

"She has her Halloween costume picked out, and we'd love to see her walking around in it. She's got a dog that's missing her. Let's bring her back, and she can address all these things, so she can be back with her family," said Gil Harrington.

Harrington was last seen wearing a black Pantera shirt, a black skirt, black tights and knee high black boots. She's five-feet-six-inches tall and weighs about 120 lbs.

Again, if you have any information about her whereabouts, call Virginia State Police at (434) 352-3455. You can also call UVA Police at (434) 924-7166.
