the department has expedited

As of Tuesday afternoon, the state lab was still analyzing evidence it has received from Charlottesville police, including nearly two dozen items and eight "known samples that we would use for comparison purposes," said Jeffrey Ban, director of the Department of Forensic Science's Central Laboratory in Richmond. Ban said that the department has expedited the case and hoped to provide authorities with results in the "very near future." But he noted the lab could spend hours or even a whole day on a single piece of evidence that may have multiple stains or hairs on it. He also said it is standard procedure to test any samples against those in their database, including those from other missing persons cases in the central Virginia area. Authorities on Tuesday released an updated wanted poster reflecting the new charge against Matthew. It says the 6-foot-2, 270-pound man was last reported driving his sister's 1997 light blue Nissan Sentra, and notes that he is said to have contacts in Virginia, Maryland, New York, Pennsylvania and Washington, D.C.
