Police have used DNA extracted from flesh found under the fingernails of 27-year-old Vanessa Marcotte to charge a man with her murder last summer. Marcotte, a Google executive in New York, was waylaid as she jogged barely half a mile from her mother’s home in Princeton, Massachusetts, where she was visiting. The ferocity of her resistance is told in the abundance evidence on her own hands which ties the crime with scientific certainty to Angel Colon-Ortiz, 31. “We got him,” Worcester County District Attorney Joseph Early Jr. said Saturday. His terse announcement was met with cheering and applause among those present. Remarkably, the DNA match was not found in criminal records. Listen to how Ortiz was caught.
