Hello, I’m Charlotte Bellis, and you’re watching Newsy.com.

Dubbed the “craigslist killer,” Philip Markoff is captivating American curiosity.

Boston police arrested the 22-year-old medical student in connection with the murder of a 26-year-old woman police say he found off the popular classifieds website Craigslist.

The murdered woman, Julissa Brisman, had advertised massage services on Craigslist.

Now, many are stunned at Markoff’s arrest, saying at least on the outside—he doesn’t fit the profile of a murderer:

“Why would a 22-year-old medical student with no apparent criminal record commit such heinous crimes?”(CNN)
“Police say by all appearances he was leading some kind of a secret double life. As you mentioned, he was living this normal outwardly.” (MSNBC)
“All signs pointed to him as being a clean cut average young man... But police say he had a much darker side.” (NBC)

ABC News reports Markoff’s fiancé sent the network an email, she suggests police have a motive in falsely accusing him:

“Unfortunately you were given wrong information as was the public. All I have to say to you is Philip is a beautiful person inside and out and could not hurt a fly! A police officer in Boston is trying make big bucks by selling this false story to the TV stations.” (ABC)

Technology blog Blackberry Cool says Markoff’s arrest is just another example of how “high-tech leads” can help law enforcement solve crimes:

Police used pictures from surveillance videos in hotels in Boston as well as Markoff’s computer IP address to lead to his arrest.

The Gawker points out another high-tech development, saying: “As is increasingly common, bloggers were able to quickly assemble a portrait of the alleged criminal online. The Boston University medical student has a Facebook page, online class schedule and a website for a wedding scheduled this August on the Jersey Shore.” (The Gawker)

Markoff will be arraigned in Boston Tuesday afternoon… He faces charges of murder and unlawful possession of a firearm.
