After a Saturday night out with friends, 28-year-old Joyce Chiang stopped at a Starbucks in DuPont Circle before walking home. That was the last that anyone saw of her. Months later, Chiang's lifeless body is recovered 10 miles downriver from Washington D.C. Despite all the media attention, the case soon went cold. Two years later, 24-year-old Chandra Levy also disappeared. Like Joyce, Chandra was a petite brunette who lived in DuPont Circle and frequented the same Starbucks. Curiously, both women interned for congressmen and both of their bodies were abandoned in D.C. parks. Does the team believe a serial killer is still prowling DuPont Circle?
