The detectives quickly identify a witness, Albert Franklin, who saw the killings from his apartment window. But they keep running into one dead end after another. And when Franklin disappears, they suspect he, too, may now be dead.

Now Shakur, who prides herself on always knowing how to behave and react, finds herself mixed up with figures from the city's underbelly. And it becomes clear that the murdered cop may have been dirty.

But if he was, that means others on the force may be, too. Could someone they know be a killer or know who is responsible? If so, they will have to be careful around even those they think they can trust.

Join the detectives as they try to uncover the truth behind a set of killings that keeps them baffled right up until the end in Duped.
