Blood doesn’t just leave a stain—it can leave a story. In this episode of The Interview Room, Chris McDonough, Dr. Brucato, and Sgt. Lamb sit down with Karen Elliott of The Cold Case Foundation for an in-depth look at Bloodstain Pattern Analysis (BPA) and how investigators use blood evidence to reconstruct what may have happened inside a crime scene. Karen Elliott Bio: https://www.coldcasefoundation.org/karen-elliott.html How can the shape, size, distribution, and location of bloodstains help investigators understand movement, impact, direction, and sequence of events? And just as importantly—what can bloodstain evidence NOT tell us? Karen breaks down the science behind bloodstain pattern analysis, common misconceptions, crime-scene reconstruction, and the importance of documenting and interpreting blood evidence properly. We’ll explore: • What bloodstain patterns can reveal • Impact patterns and projected blood • Directionality and angles of impact • Cast-off patterns and movement • Passive bloodstains and transfer patterns • How investigators document blood evidence • The role of photography and crime-scene reconstruction • Common mistakes and misconceptions • How blood evidence can support—or challenge—a theory of the case • The limitations of bloodstain pattern analysis • How this evidence can be used in cold-case investigations This is a fascinating look at one of the most misunderstood areas of forensic investigation. The Interview Room brings investigators, forensic experts, prosecutors, authors, and other professionals together to examine the evidence and ask the questions that matter. Join Chris McDonough and Karen Elliott for a deep dive into the science behind the stains. #BloodSpatter #BloodstainPatternAnalysis #Forensics #TrueCrime #ColdCases #CrimeScene #TheInterviewRoom 👉 Follow us for FREE on Spotify: https://open.spotify.com/show/3DlOOFE5Ko3rj8oetl4xBt ❤️ LIKE if you want more real investigative interviews 💬 Drop a respectful comment below 🔔 SUBSCRIBE & turn on notifications 📲 Share this with someone who loves cold cases 🎙️ Chris McDonough & Karen McDonough – The Interview Room ✅ Chris McDonough Bio: https://www.coldcasefoundation.org/chris-mcdonough---law-enforcement-relations.html ✅ Karen McDonough Bio: https://www.coldcasefoundation.org/karen-mcdonough.html For Business Inquiries Only: info.theinterviewroom@protonmail.com * If you send us an email, we cannot guarantee that you will get a response due to the high volume that we receive.
