5 Lessons I Learned as a Murder Investigator

Now that I’ve written my debut crime thriller, I’ve been reflecting on the lessons I learned as a murder investigator and how those lessons shaped my writing.

I began investigating Class 1 Felonies in Washington, D.C., in the early ‘90s when D.C. was considered the “murder capital” of the United States. Over 450 murders, mostly gang-related, were committed the year that I showed up at the ripe old age of 24 to work as the legal equivalent of a private investigator for the Public Defender’s Service (PDS). With nothing but my admission letter to Georgetown Law School, a deep well of idealism about the criminal justice system, and a laminated card declaring me an investigator, I set out into the worst neighborhoods of D.C. to investigate murder.

Before I went out in the field, the PDS provided me with a few weeks of training in the techniques and legal technicalities of the job. During that training, I learned more about the criminal justice system than I learned in any law school class. For example, a huge part of my job was to make sure I didn’t accidentally take a written statement that implicated our client so that we wouldn’t have to share that information with the prosecution during discovery (basically, when the defense and prosecution have to share information with each other). My first lesson:

1. The tension between police, prosecutors, and defense lawyers is not a fiction created by TV drama. The adversarial criminal justice system is often genuinely adversarial.

After training, I was given a partner, and we were assigned three lawyers to assist. On my first day in the field, I spent the entire afternoon playing with a toddler—definitely not what I expected. We needed to get a written statement from the child’s mother about a drive-by shooting she had witnessed, and we didn’t want the little girl to be there during that detailed conversation. So, I took the girl in the other room to play while my partner took the mother’s statement.

After the interview, we learned that the toddler had actually witnessed the murder firsthand. Even later, I learned that she was the victim’s daughter. That giggling little girl had watched her own father gunned down right in front of her. My first day turned out to be a perfect introduction to my second lesson:

2. Investigating murder is an inherently heartbreaking, gut-wrenching job. Something I try to remember when I’m writing about all the people involved, from cops to innocent bystanders.

While I spent some time on stakeouts and interviewing suspects, the vast bulk of what I did was tracking down and taking statements from witnesses, building a timeline of the events surrounding the murder, and requesting case files in the courthouse. Between all the mundane legwork, I did have a gun pulled on me, and I was almost caught up in an ATF raid. Lesson number three:

3. Investigation involves day after day of tedium punctuated by very brief moments of abject terror!

My experiences absolutely changed my perspective on the criminal justice system. I struggled with things I saw on both sides of the fence of the adversarial court system, and I realized that I didn’t actually want to become a lawyer (hello Ph.D. in anthropology instead). Despite the flaws I saw in the system, I was awed by the amazing lawyers, police, and judges that I met. Which leads to my fourth lesson:

4. The criminal justice system works because of the blazing icons of idealism and dedication that make it happen every day.

Despite the tedium, it really was incredible opening a new file and reading reports, taking witness statements, processing crime scene data, watching autopsies, and compiling all the information gathered during a murder case. So, last but not least, my fifth lesson:

5. Despite the gut-wrenching horror of any murder, the investigative process really is like a puzzle that needs to be pieced together to tease out the truth.

That human drama coupled with the questions surrounding any murder (especially the who and why) is ultimately why I love reading, and now writing, mysteries!

    I’ve just been reading Just Mercy by Bryan Stevenson and the parallel interests of crime investigators, lawyers, and the criminal justice system sounds like it would have interesting connections.

  31. Andrew Jensen

    Our justice system is certainly a behemoth. Everyone connected to any crime is changed by that crime. It’s one of the reasons I like crime procedurals that mimic real life.

    it’s nice to have a real life look at crime as a background when reading fictional mysteries, as a way of being able to judge its closeness to real life circumstances, as opposed to exaggerated or even ludicrous scenarios .

    I retired from the Juvenile Unit of the Police Department and as bad as I witnessed, I imagine you saw a lot worse. This book sounds like one I will definitely be reading and I’ll set aside a huge block of time so that I won’t be disturbed while reading.

  107. Irene Menge

    Wonderful post. I’m intrigued.

  108. Myra Ball

    You truly have an inside perpective. I think the hardest part of being an investigator would be keeping some sort of empathy. I think seeing the traumatic would desynthetize an investigator. Sometimes it’s hard to hold on to our humanity. Caged sounds like a winner and Congrats on your first book. That’s an accomplishment.

  109. CherokeeP

    I took a Murder/Violent Crime class while working on my degree. You truly are an amazing person to do what you’ve done, and brave! I worked two years as a Sheriff Deputy and now do Adult Protective Services. It is humbling to deal with people when they are at their worst.

  110. Suzanne McMannis

    Interested.

  111. Michael Carter

    Interesting post.
    Please enter me in this sweepstakes.
    Thanks!

  112. Amber Gentry

    I like the 2nd point she made. So often I get wrapped up in the mystery and the story, and I forget that real-life murder has real-life consequences. It’s important to remember that crimes involve real people with real heartache, grief, and death.

  113. Louis Burklow

    I’d enjoy reading this kind of book by someone who knows how these investigations go in real life.

  114. Michelle Herman

    Sounds interesting. Thanks for the chance!

  115. Karen Hester

    excellent post

  116. Jennifer Sakurai

    I can’t help but wonder how that child behaved that afternoon…she saw her father killed and was separated from her mother for a long time while the mother was giving her statement. Sometimes the effects appear later, I would think. Depends on the age and the child’s personality, I suppose.

  117. Sandra Brossart

    I am looking forward to anything you write – judging by this post, all will be interesting to me.

  118. Cindee

    Goes to show .. not all teaching can be read in books.. thanks for sharing your experiences.. Can’t wait to read your book

    Sounds like my kind of book, written by someone who has actually been there and done it.

  124. Melinda

    Already have this on my tbr!!

  125. Cherie Gravette

    This sounds like a “cannot put down” book! Thanks for this chance!

  128. Deb Philippon

    This is the sort of book I really enjoy reading. For me, a person’s experiences in such an interesting field is an absorbing read.

  129. Teresa Young

    Quite a background of experience – mostly tedium, a few moments of terror, sums it up.

  130. Sharon Mullennex

    Thank you for the wonderful lessons you posted. I had thought of going into the legal field then changed my mind because of those reasons. I look forward to reading your first book.

  131. Renee

    Having beeb a prosecutor, your points wring true.

  146. Karen Terry

    Sounds like an interesting read.

  147. Susan Wise

    Definitely need to read Caged…looks like interesting book.

  148. Sheila

    This was interesting from an investigator’s point of view, and as the sister of a murder victim from the 80’s, I respect all of the hours that go into an investigation.I worked in federal prisons for a number of years, which was also quite an eye-opener.

  149. Vicki Wurgler

    book sounds great thanks
