CHARLOTTESVILLE, Va. (AP) _ The parents of a Virginia Tech student who was killed after attending a Metallica concert in 2009 in Charlottesville are making new claims against a security company. The allegations are contained in an amended lawsuit filed by the family of Morgan Harrington, whose remains were found in January 2010 in a farm field. They are seeking $3.9 million from RMC Events Inc., which provided security for the concert at John Paul Jones Arena. In the amended claim released Tuesday, the Harringtons said their 20-year-old daughter suffered a head wound at the concert and was bleeding and disoriented when she left the arena during the concert. The lawsuit contends Harrington was refused re-entry even though she clearly needed medical attention. RMC did not immediately respond to the lawsuit.
