( CNN ) -- The parents of a Virginia Tech student who disappeared last month during a Metallica concert asked Wednesday for volunteers to help conduct a community search this weekend . Morgan Harrington , a 20-year-old education major , went to the concert at the University of Virginia 's John Paul Jones Arena in Charlottesville , Virginia , on October 17 . Police said they are continuing to follow leads in the case , but have no new information . `` We will stop at nothing until she is found , '' Harrington 's father , Dan Harrington of Roanoke , Virginia , told reporters Wednesday . During the concert , Harrington left her friends to use the restroom , Virginia State Police spokeswoman Corinne Geller said Wednesday , and when she did not return they called her on her cell phone at 8:48 p.m. She told them she was outside the arena and could not get back in because of its policy , Geller said , but told them not to worry about her and that she would find a ride home . There are restrooms inside the arena , Geller said , and police do not know how or why Harrington got outside . Witnesses who saw her outside the arena said she did not appear to be with anyone , Geller said . At about 9:30 p.m. that night , witnesses reported seeing a person matching Harrington 's description walking on a nearby bridge , Geller said . No further sightings were reported . Harrington 's purse , with her identification and cell phone inside , was found the following day in an overflow parking lot near the arena , Geller said . A friend had driven Harrington 's car to the concert , she said , and so was still in possession of the car keys when they got separated . Police would not say whether Harrington was intoxicated . A $ 150,000 reward has been offered for information leading to Harrington 's whereabouts , Geller said . Of that , Metallica contributed $ 50,000 . Authorities have received more than 350 leads since Harrington disappeared , Geller said . She was reported missing the day after the concert , when she did not show up at her parents ' home to study for a math exam with her father . Working with police and the Texas-based Laura Recovery Center , the Harringtons organized the community search to begin Friday and reconvene Saturday or Sunday . The couple was joined at the Wednesday press conference by Ed Smart , whose daughter Elizabeth was abducted in 2002 . She returned home nine months later after police found her in the custody of suspect Brian David Mitchell and his wife , Wanda Barzee . `` When a child is missing , you have no idea of what to do and how to move forward , '' Smart said , calling it `` the club that nobody wants to belong to . '' `` There is n't a parent out there that would want to be in his position , '' he said of Harrington . `` The importance of it is , there 's a girl that is lost out there that needs to be found . '' Harrington said he reached out to Smart last week to seek advice on how to go through the disappearance of a child . Smart has been supportive and helpful , he said , and offered to come to Virginia and speak to reporters Wednesday . Gil Harrington spoke briefly . `` Morgan , two-for-one , '' she said , referring to a motto on a Web site set up by the family , www.findmorgan.com : `` I love you too much , forever and once more . '' `` We are trying to find you , '' she told her daughter . `` We will never stop . We are trying , honey , hang on . And to the person who has taken Morgan from us , please just let her go . '' Dan Harrington said Smart 's story had provided them with hope . `` People do come back , '' he said . `` Not everyone is lost . We have to hold out hope that our daughter will return to us . '' Smart told reporters he never lost hope that his daughter was alive , but `` that does n't mean there was n't doubt at times . '' `` I believed she was still out there and felt that she would come home , '' he said . `` That 's what we 're hoping for with Morgan . We just want to see her come home ... I believe that somebody can help us . '' Harrington is 5 feet 6 inches tall and weighs 120 pounds , with blond hair and blue eyes . She was wearing a black Pantera T-shirt , a black miniskirt , black tights and black boots when last seen .
