New York serial killer thought to be real-life ‘Dexter’

With summer approaching, a cunning, vicious and prolific serial killer is on the loose in New York City--a sadly familiar refrain--and experts believe he may be someone well-versed in forensic investigations. In other words, Gotham may have its own real-life "Dexter" on the loose, responsible for the deaths of at least four women, possibly eight.

This victims of this particular killer have all been prostitutes--a target of serial killers dating back to the days of Jack the Ripper--who marketed their services on Craigslist. And in the past two days, both the New York Post and the New York Times have cited law enforcement sources saying that they believe the killer could be one of their own, or at least someone who has taken the time to educate themselves on murder investigations.

Police say when the killer has made calls to family members of his victims to taunt them, he's done so from high-density areas in Manhattan like Times Square and Penn Station, where it's much more difficult for police to trace his calls and he can easily blend into crowds. Police say the killer also used disposable cell phones to communicate with his would-be victims.

"He is a guy who is aware of how we utilize technology," one investigator told the New York Times. "Frankly, people are thinking maybe he could be a cop ... Without question, this guy is smart, this guy is not a dope ... It's a guy who thinks about things."
