Accused Craigslist killer Philip Markoff has been formally charged with murdering 26-year-old Julissa Brisman, the Boston Globe reports. The former med student is being arraigned today on seven charges, including first-degree murder, in connection with Brisman’s death and another attack on a prostitute. Both women advertised their services on Craigslist, where Markoff, 23, found them. Prosecutors say fingerprints and video footage link Markoff to the crimes. (More Craigslist stories.)
