About Killer Instinct

Killer Instinct is a true crime podcast in which Savannah, its host, rebuilds murder cases from the evidence investigators gathered. Episode titles pair a hook with a name. Read together, titles such as 'Love and Betrayal : Devon Guzman', 'A Tragic Friendship : Jessie Blodgett' and 'Murder of Husband # 5 : Joe and Sarah Hartsfield' show a steady pull toward cases tangled up in love, marriage and friendship. The storytelling focuses on the mechanics of each investigation. In the Jennifer Keese case, a parking-lot camera records a driver backing out to straighten his car, waiting exactly 32 seconds, and walking off toward Jennifer's complex. The footage was too poor to identify him, so investigators had people of different heights walk past the same gate, settling on a man between five foot three and five foot five. 'A Headless Mystery: The Dermond Murders' works the clock instead. Grocery store footage, a newspaper found on the kitchen table with the crossword apparently begun and an email opened on the morning of May 2nd let police narrow the window for the crime to a span ending just before a Derby party. A house left intact, valuables still in place, made a robbery gone wrong hard to credit. Phone records drive the Shea Briar story. Detectives already knew EJ had placed the last call to Shea shortly after midnight, yet they let her lie about it without pushing back, simply to see what she would say. Then a woman who had known EJ for years came forward with more. Savannah stops to spell out why a detail like that lie looked like a red flag, which keeps a long chain of evidence easy to track. Biography sits beside the procedure. The Hartsfield case moves through Sarah's marriages, with Joe as her fifth husband, plus an army enlistment at 22 and an affair during a deployment. It also recounts an alleged incident at a house that never led to a charge, since, as Savannah puts it, there is no such thing as attempted arson. In the Devon Guzman case, an exchange of rings between Devon and Michelle sours into an argument at Devon's dad's house once Michelle learns Devon is not leaving Carrie. The Jessie Blodgett episode widens to a separate attack three days earlier in Richfield, Wisconsin, where a woman walking her dog saw a man she had noticed sitting in a van run toward her with a knife. The bookends are informal: a hello to newcomers, reminders to subscribe, and a sign-off telling listeners to stay safe. Savannah says new episodes arrive on Wednesdays, with a video version on YouTube and a Patreon for exclusive episodes. What a listener gets is the case file, walked through with the reasoning left in.

Made for: Suits a listener who wants true crime told as a careful walk through investigative evidence, with timelines, camera footage and phone records explained, and who likes a friendly, informal host at the start and end of each case.

What sets it apart: It stays close to the working parts of an investigation, like a 32-second wait on a parking-lot camera or a last phone call a suspect lied about, and Savannah stops to explain why each detail mattered to police. A casual greeting and sign-off frame the case.

In their own words

Every Wednesday, join Savannah Brymer as she delves into the gripping and mysterious world of true crime, where each case uncovers hidden truths and unexpected twists. From infamous serial killers to haunting missing person mysteries, Killer Instinct goes beyond the headlines to seek justice and uncover the emotional depths of each story. With meticulous research and heartfelt storytelling, Savannah sheds light on untold tales of resilience, loss, and the relentless pursuit of truth, inviting listeners to journey through the darkest corners of human nature—and the strength of those left behind.

New DNA Evidence : Jennifer KeeseApr 15, 2026

A surveillance clip and possible new evidence keep Jennifer's case focused but unresolved.

Jennifer's case hinges on a surveillance clip that gives investigators just enough to follow: a driver waits exactly 32 seconds, gets out, and walks back toward her complex.

A Headless Mystery: The Dermond MurdersApr 8, 2026

A narrowed timeline and an untouched home make the Dermant case feel more unsettling than a robbery story.

Russell and Shirley Dermant's case is built from small, ordinary details that steadily tighten the window around the crime. Savannah tracks how investigators placed the violence between the early afternoon of May 2 and the early afternoon of May 3, drawing on a delivered…

Custody and Coercion : Shea BriarApr 1, 2026

A phone record and a babysitting request deepen the suspicion around Shea's murder.

Murder of Husband # 5 : Joe and Sarah HartsfieldMar 25, 2026

A fifth marriage frames a grim account of family violence, an arson allegation, and delayed accountability.

Love and Betrayal : Devon GuzmanMar 18, 2026

A ring exchange in Puerto Rico sets a tense relationship conflict on course for a volatile meeting.

In Puerto Rico, an exchange of rings turns into the hinge point for a strained relationship conflict involving Devon, Michelle, and Carrie. The episode tracks Michelle's reaction after learning Devon did not intend to end things with Carrie, then follows the attempt to talk it…
