The ISP, Comcast, (again, after another subpoena) then handed over the name and physical address of the person with that IP address: Philip Markoff. It was a throwaway email account, but, after a subpoena, Microsoft handed over the IP address of the person who registered it. Going after the email address that the killer used to contact Julissa was more fruitful. In the end, it proved to be a dead end: Markoff, it turned out, had used multiple disposable phones. This was and still is a controversial practice, one thatвЂ™s raised alarm bells by the ACLU and the NY Times, among others. They tried to find a single phone number that was active in each location around that time. To start, the FBI pulled cell tower records near the scene of each crime for 15 minutes before and after each incident. To identify Markoff as the man in the surveillance footage-and thereby catch the Craigslist Killer-required the use of several forms of digital forensics.Дigital Forensics Leads Investigators to the Craigslist Killer According to McAllister, he rarely left the house.

Many people in the student-rich city of Boston looked like Philip Markoff did: young, tall, and white.

Investigators scanned through security footage from all three locations around the time of the crimes (which you can see for yourself, here).ДЇrom there, they identified what they believed to be the same man across all three: a young, tall, white male in a dark jacket and a baseball cap. And just a few days later, they connected it yet again to an attempted robbery in a Rhode Island hotel. Investigators soon connected JulissaвЂ™s murder to the armed robbery of an escort at another Boston hotel a few days prior. This was the only murder committed by Philip Markoff, a man who would come to be known as the Craigslist Killer. Upon arriving at the hotel room, however, JulissaвЂ™s client bound her, gagged her, robbed her, and then put bullets through her heart, her hip, and her lung.

The appointment had been set up through Craigslist. On the night of April 14, 2009, Julissa Brisman showed up at a Boston hotel room, intending to give her new client a massage.
