The Raven Murders

In a city ravaged by the greatest number of murders in over a decade, a shooting incident at a sprawling public housing project leaves three teenage gang members and four adults dead. Two officers are critically wounded. The public is shocked and demanding an end to the carnage.
NYPD Capt. Dan Dragona and his Violent Crimes Unit are assigned to investigate what initially appears to have all the markings of a gang dispute over drug dealing turf.
A shocking discovery challenges that theory.
Among the adults shot to death in an apartment, one victim is identified as a South American political activist. Top secret government intelligence sources report he was transporting a dossier to be turned over to the State Department. It reportedly detailed the recent purchase of missiles from Middle Eastern terrorists that would be used for an attack against the United States.
Were these murders drug gang related, or was the motive fueled by international extremists who would kill to keep their intentions hidden?
