In 2008, Edmonton, Alberta became the center of a bizarre and disturbing murder investigation involving filmmaker Mark Twitchell. What initially appeared to be the disappearance of 38-year-old John “Johnny” Altinger would eventually expose a shocking story involving fake online dating profiles, deception, and a murder that prosecutors said was inspired in part by the fictional world of Dexter.
In this episode of Stuttering in Silence, Gavin and Matt break down the timeline of the Mark Twitchell case, from his life as an aspiring filmmaker and his fascination with Dexter to the online deception that brought Altinger to Twitchell's garage. They examine the evidence investigators uncovered, the infamous “SKConfessions” document found on Twitchell's computer, the investigation that ultimately exposed him, and the trial that followed.
Was Mark Twitchell attempting to turn fiction into reality, or was the Dexter connection exaggerated after the fact? Join Gavin and Matt as they explore one of Canada's most unusual and disturbing murder cases and the investigation that exposed the man behind the carefully constructed façade.

Curtain Call for Murder: The Daniel Wozniak Case
In May 2010, what should have been a weekend of celebration turned into one of Southern California's most shocking murder investigations. Just days before his wedding, aspiring actor Daniel Wozniak carried out a calculated plan that left two innocent people dead: Army veteran Samuel Herr and college student Juri Kibuishi. Prosecutors alleged that Wozniak targeted Herr for his savings, then murdered Kibuishi in an attempt to frame Herr and cover his tracks. The investigation quickly unraveled the deception, exposing one of the most disturbing murder-for-financial-gain cases in recent California history.
In this episode of Stuttering in Silence, Gavin and Matt break down the complete timeline of the Daniel Wozniak case—from the murders inside the Los Alamitos Joint Forces Training Base, to the elaborate cover-up, the investigation that uncovered the truth, and the courtroom proceedings that followed. They examine the motive, the evidence, and the chilling decisions that transformed a respected community theater actor into one of California's most infamous killers.
How did greed and desperation lead to such an elaborate and horrifying crime? Join us as we explore the lies, the investigation, and the devastating impact left on the families of Samuel Herr and Juri Kibuishi in a case that remains unforgettable.
