State Police say forensic testing has linked a t-shirt found in Charlottesville to Morgan Harrington.
The black t-shirt is the one Harrington was last seen wearing the night of the Metallica concert before she disappeared.
The shirt was found in November, a month after she disappeared. Harrington's body was found in January in Albemarle County.
State Police say they have pursued about 1,000 leads as part of the investigation.
