Unsolved Serial Killers Vol. 4 continues D.R. Werner’s chilling deep dive into some of the most haunting and perplexing murder cases that remain unsolved. Just like the previous volumes, this book masterfully balances meticulous research with gripping storytelling, drawing you into each case with a mix of curiosity and dread.
What stands out most is Werner’s ability to bring these real-life mysteries to the page without sensationalizing them. The writing is clear and compelling, giving readers both the facts and the unsettling atmosphere surrounding these crimes. Each chapter feels like peeling back the layers of a mystery that refuses to be solved, and the unanswered questions linger long after you finish reading.
The strength of this volume lies in the variety of cases covered. From lesser-known killers who slipped under the radar to more notorious figures still shrouded in mystery, Werner ensures that every chapter feels fresh and engaging. The detailed timelines, victim backgrounds, and investigative challenges provide a complete picture that makes the frustration of these cold cases all the more real.
That said, the book can at times feel slightly repetitive in structure if you’ve read earlier volumes, which is why I held back from a full 5-star rating. Still, the consistency and depth are also part of its strength—fans of true crime who enjoy clear, factual storytelling will find this to be a solid and worthwhile addition to the series.
Overall, Unsolved Serial Killers Vol. 4 is haunting, fascinating, and deeply thought-provoking. It’s a reminder that not every story has closure, and sometimes the silence of the unknown is what chills us the most.
📚 Highly recommended for true crime enthusiasts who want a well-researched, captivating look into the dark mysteries that remain unsolved.

Finally reading the fourth volume! This one contains another 10 serial killers which I haven't heard of. Normally I have heard about one or two of them, but not this time.
The 10 cases are:
🛑 The Colonial Parkway Murders
🛑 The Oakland County Child Killer
🛑 The Disappeared or Isère
🛑 The B1 Butcher
🛑 The Eastbound Strangler
🛑 The Paraquat Killer
🛑 The Mad Butcher of Kingsbury Run
🛑 The Belize Ripper
🛑 The Lódz Gay Murders
🛑 The Family Murders
I devoured this book, I loved reading about all of these cases. Such sadness in many people's hearts. From children to teens to adults and the elderly. Such a shame. Hopefully one day those who's bodies haven't been found will be found so they can have a decent burial. And hopefully those have commited these heinous crimes will be found and punished.

Forget a mad mad world.....it's a sick sick world.
Each time I read one of these books, I'm reminded that not every person you meet wants to be your friend. It seems that the more years go by, the crueler people are towards those they deem as weak. We need to keep our eyes open and watch carefully.

Okay
Just basic overview of most cases. The most interesting but least discussed is The Family Murders. It seemed to run out of focus. There was little support that the cases were committed by a group.

Decent read
I always find serial killer stories to be sick and sad. Unsolved stories are all the more disturbing. How sis these psychos escape justice? Where are they now?
