A 23-year-old Boston University medical student, Philip Markoff, believed to be the "Craigslist Killer," will be arraigned today.

Police claim that Markoff killed Julissa Brisman last Tuesday inside a Boston hotel during an alleged robbery. Markoff, labeled by the media as a "nice, clean-cut guy," was engaged to be married August 14, 2009, to his beautiful "all-American" fiancé, whom he met at undergraduate school. As more details of Markoff’s life become public, people are further jarred by the alleged dark side of this young man.

Markoff and his fiancé, Megan McAllister, have a wedding website, which features quizzes about their relationship, information about their honeymoon, where they plan to wed and also how they met. The website reads:

We met while going to college at University at Albany together. Megan was a senior and Phil was a sophomore. Our apartment buildings were right next door and we didn’t even know it until we met one day at the hospital. We both started volunteering at the hospital on September 19, 2005. We volunteered at the Emergency Room together and spent about 2 months pushing stretchers down hallways and bringing blood and urine samples to pathology together before our first date on November 11, 2005!!

According to reports, Markoff was from upstate New York but now resides in Quincy, near Boston, and expected to graduate from BU medical school by 2011. Boston University has confirmed his suspension.

On Monday, Markoff was officially charged with the murder of Brisman. Brisman, a 26-year-old New York masseuse who reportedly advertised her services on craigslist.org, was shot dead at an upscale Boston hotel. The Daily News reports that Markoff will also be charged with kidnapping and robbery in an attack four days earlier in another luxury Boston hotel. The victim was an exotic dancer who also advertised online.

Police suspect that there are more victims out there and hope they come forward.
