In a luxury Boston hotel on April 14, 2009, police discovered the body of a beautiful young woman--her head battered, a bullet through her heart. The victim, a masseuse, had advertised her erotic services on the popular website Craigslist. Authorities were on high alert--there had been a string of women with connections to Craigslist that had been attacked throughout Boston. Elsewhere, handsome 22-year old Boston University medical student Philip Markoff was making plans to marry his fiancée.
