Familial DNA in criminal investigations (Guest post by D.J. Swykert)

As a crime fiction reader, I’ve always been intrigued by DNA and how it is used to capture and prosecute criminals. Today, I want to welcome novelist David J. Swykert, the author of the crime novel “The death of anyone“, who has agreed to share some of his research in the field of DNA forensics.


Unique DNA Search Catches the Grim Sleeper


The underlying theme in “The Death of Anyone“, Melange Books, poses the Machiavellian question: Does the end justify the means? Bonnie Benham, the lead detective in my story, has her own answer. But the legality of this question was answered in a real life courtroom in the California trial of a serial killer dubbed by the media: The Grim Sleeper.

Lonnie David Franklin, the Grim Sleeper, was caught because his son’s DNA was the closest match to DNA collected at the crime scenes in the database. Investigating Franklin’s son led them to investigate Lonnie Franklin. But there was no direct DNA evidence that linked Lonnie to the crime scene until they obtained a sample from him after his arrest. Lonnie Franklin is the first person in the U.S. to ever stand trial for murder based on this type of evidence, and its admissibility issues were thoroughly tested by defense attorneys.

Only two states at this time, California and Colorado, have a written policy concerning the use of Familial DNA in an investigation. The admission of Familial DNA, with its potential Fourth Amendment violations, has never been tested in court. The California trial of Lonnie David Franklin will become a landmark case for the future use of Familial DNA Searches by law enforcement agencies nationwide.

Lonnie David Franklin, AKA, The Grim Sleeper, was arrested on July 7, 2010. The Los Angeles District Attorney’s Office charged him with ten counts of murder, one count of attempted murder, and special circumstance allegations of multiple murders in the cases. A grand jury indictment was issued on March 23, 2011. The Grim Sleeper has been resting comfortably in jail since his arrest awaiting trial; the large quantity of evidence in this case, some dating back thirty years, has caused a lengthy pretrial discovery. The trial was originally scheduled to begin the summer of 2014, but was put on hold. It was rescheduled for June 30, 2015, but that didn’t happen. On Monday August 17, 2015, at a pretrial hearing, the trial was rescheduled for October 14, 2015. Finally, in the late spring of 2016, The Grim Sleeper was convicted in May of 2016 and received the death penalty. The death sentence was later upheld by the court in August of 2016. A long appeals process, which might ultimately end up with the Supreme Court, is expected.

I first heard of the technique while working as a 911 operator in 2006. It came up in a conversation with our CSI investigator in the department. I thought at the time it would make an interesting premise for a book. I began writing the mystery some three years later after leaving the department. I had just finished editing a first draft of The Death of Anyone in the summer 2010 when news of The Grim Sleeper’s capture in Los Angeles was released. I read with interest all the information pouring out of L.A. regarding the investigation and the problems confronting prosecutors. All of which are explored in The Death of Anyone.

In my fictional story Detroit Detective Bonnie Benham has been transferred from working undercover in narcotics to homicide and is working the case of a killer of adolescent girls. She is a straight forward investigator who describes herself as a blonde with a badge and a gun. CSI collects DNA evidence from the scene of the latest victim, which had not been detected on the other victims. But no suspect turns up in the FBI database. Due to the notoriety of the crimes a task force is put together with Bonnie as the lead detective, and she implores the D.A. to use an as yet unapproved type of a DNA Search in an effort to identify the killer.

“The Death of Anyone” is available on the Melange Books website and also on Amazon.com in Kindle and print, Barnes & Noble, Smashwords and Kobo.
