Serial Killer Again?

Or is this one of the stranglers that never got caught?

• Chicago police are investigating whether four women found strangled in vacant buildings over the past two years were killed by the same attacker, authorities said Tuesday.
  
  Three of the attacks are linked by evidence, while the most recent slaying last weekend fits the pattern, though forensic testing has not been completed, said [meri-clout-orious] Calumet Area Lt. Anthony Carothers [D-Ike (prison)]
  
  The women have been found strangled in vacant or abandoned buildings in the Roseland and West Pullman neighborhoods, police said.

All of the victims have extensive "high risk" lifestyle choices in their past.

And due to a recent "reclassification" directive, supernintendo J-Fled has declared that these "indoor" homicides were unpreventable and there really isn't much the police could have done anyway.
