Dexter and the Insanity Defense: "I Really Need to Kill Somebody"

[First read the introductory post, Meet Dexter Morgan.]  Several times throughout the series, Dexter finds himself just a hair—or fiber or blood drop—away from getting caught.  In season two, for example, FBI Special Agent Frank Lundy comes close to discovering that Dexter is the Bay Harbor Butcher.  And if the Feds and Miami Metro were able to link all of those dead bodies to Dexter, what defense could he possibly have?  More specifically, could Dexter successfully argue that he was insane and therefore not legally responsible for his multiple homicides?

Dexter, Miami Metro, and the Broken Chain of Custody

[First read the introductory post, Meet Dexter Morgan.]  In “Dex Takes a Holiday,” Dexter uses his three-day mini-vacation away from Rita to target his next victim, Zoey Kruger.  (This, Dexter explains, is a serial killer’s way of recharging his batteries.)  But Zoey isn’t Dexter’s typical victim.  Instead, she’s one of his own: a cop.  Granted, she’s a bad cop—one that killed her husband and child to escape the unbearable suffocation of domesticity—but a cop nonetheless.  Dexter begins, as he usually does, by gathering solid evidence.  While prosecutors like Miguel Prado may go after defendants by filing a criminal complaint first, and then creating evidence later, Dexter is more careful.  He knows that his targets face a stiffer penalty than all but a handful of Miami’s criminal defendants.  So when Zoey puts her house on the market—after all, who needs four bedrooms and a big yard when you’ve just murdered your husband and daughter?—Dexter attends the open house.  While there, he gets what he needs: physical evidence.  He finds a small part of the glove that Zoey wore when she did the deeds.  The glove fragment has the gunshot residue and the blood evidence necessary to link Zoey to the double murder—the proof that Dexter’s moral code requires before he can drug Zoey, immobilize her, stab her, slice her into neat little pieces, and send her to her final home below sea level.

Meet Dexter Morgan

Not all book ideas grow up to be books.  I recently wrote a proposal for a law-related book about Showtime’s Dexter.  As a Miami Metro Police Department blood analyst by day, and a serial killer by night, Dexter Morgan found himself buried in legal issues—a lawyer-writer’s dream.  Although several publishers really liked the proposal, so far they’ve all passed on the project.  It turns out that in publishing, as in much of life, timing is everything.  Because Showtime recently announced that Dexter will end its eight-year run later this year, and because books can take nearly a full calendar year to get to print, the publishers thought that my Dexter-themed book would be too late to the dance.  (I respectfully disagree, as the season eight DVD won't be released until next summer.  Besides, academics are still writing about Buffy the Vampire Slayer a full decade after Sarah Michelle Gellar hung up her stake.)  But blogs, unlike books, are near instantaneous.  And with Dexter’s final season now in full swing, I thought that fans of the show might enjoy the two short chapters that I wrote for the book proposal.  The chapters—one on Dexter and the chain of custody and one on Dexter the insanity defense—are, obviously, about a fictional show, not legal advice, and purely for entertainment purposes (unless, of course, any of you Dexter fans and Legal Watchdog readers are also publishers, in which case you should contact my literary agent for a copy of the book proposal).  So enjoy the two chapters that will follow immediately after this post.   

Dexter, DNA, and Maryland v. King

Dexter is a blood analyst for the Miami Metro Police Department by day, and, unbeknownst to nearly everyone, is also a serial killer by night.  With that type of work, it’s no wonder that television’s most beloved murderer, and his workaday colleagues at Miami Metro, are buried in legal issues.  Take, for example, the time that both Miami Metro and Dexter were tracking the Trinity Killer—the mysterious killer that always took three victims in each of his murderous cycles.  Miami Metro had a great idea: employ the “DNA sweep.”  The cops simply set up “DNA roadblocks” on the highway, stopped all of the cars, and forced everyone to submit their DNA to be tested against the DNA left behind at one of Trinity’s crime scenes.  (In the end, that’s not what caught Trinity—Dexter got to him first and delivered his own brand of serial-killing justice.)  I remember laughing aloud when seeing this Miami Metro police practice.  Even in today’s over-the-top, short-sighted, hysterically tough-on-crime society, these DNA sweeps would never be allowed—or so I thought.  And then our Supreme Court decided Maryland v. King.
