Protokoll IV (i FUP:en 1989) - Kriminalteknisk redovisning (sidan 3 och 4):
På Sveavägens trottoar ca 50 cm väster om huslivet kvarteret ''Träsket'' och nästan mitt i Tunnelgatan finns en kraftig blodsamling som är ca 240 cm lång och 70 cm bred på det bredaste stället. Blodet som nu är fruset har runnit mot Sveavägens trottoarkant. Söder om blodsamlingen finns ett 50-tal blodstänk, de flesta med stänkriktning söderut - nästan i Sveavägens längdriktning mot Konserthuset. Blodstänken finns på en yta som är ca 250 cm bred och 500 cm lång. Bloddropparna varierar i storlek från risgrynsstora upp till en tioörings storlek.

Fråga till ChatGPT:
I am doing a forensic bloodstain analysis. A victim was shot in the back. An inch above the heart. From a distance of less than one feet. The trachea was shot off and the aorta and the esophagus were damaged. Small bloodstains (about 50 of them) were found in an almost rectangular area in front of the victim. The area was 2.5 meters broad and 5 meters long. Was that likely to be expirated spatter or gunshot spatter?
Svar från ChatGPT (ChatGPT:s fetstil och kursivstil):
Let’s go through this carefully and systematically.
Summary of the case
- Gunshot wound: To the back, about 1 inch above the heart
- Range: Close range (< 1 foot)
- Structures damaged: Trachea, esophagus, aorta
- Bloodstains: ~50 small stains in a rectangular area in front of the victim, approx. 2.5 m × 5 m
- Question: Were these stains likely expirated spatter or gunshot spatter?
Step 1: Nature of the injuries
These injuries are highly significant:
- Aorta damage: Causes massive internal bleeding into the chest cavity.
- Trachea and esophagus damage: Opens a direct pathway for blood from the chest into the airway.
- Therefore, blood would enter the respiratory passages and could be expelled via breathing, coughing, or exhalation after the shot.
That means an expirated mechanism is definitely possible here.
Step 2: What gunshot spatter would look like
Gunshot spatter (especially from a close-range shot):
- Produces many very fine droplets (hundreds to thousands).
- Typically forms a cone-shaped pattern aligned with the bullet’s trajectory.
- High-velocity impact - mist-like stains (<1 mm).
- Usually much denser near the impact or exit site.
- Pattern shape tends to be narrow and directional, not rectangular and spread across several meters.
Your description — only 50 small stains over 2.5 × 5 m — doesn’t match typical gunshot spatter characteristics. That’s too few stains, spread too broadly, and in front of the victim rather than along the wound’s trajectory.
Step 3: What expirated spatter would look like
Expirated blood spatter occurs when blood from the lungs, mouth, or airway is expelled under air pressure (from breathing, coughing, or gas escape).
Typical features:
- Droplet size: small to medium (often 1–3 mm, not mist-like).
- Number of stains: relatively few compared to gunshot spatter.
- Distribution: forward of the victim’s face or mouth; can spread several meters depending on force.
- Shape: may appear in a loose, rectangular or fan-like area, depending on airflow or body movement.
- Composition: sometimes shows air bubbles, dilution (saliva/mucus), or lighter coloration on microscopic exam.
Given your case:
- The blood was found in front of the victim.
- The trachea was destroyed (blood and air would mix).
- The pattern is broad and rectangular (not tight and conical).
- Only about 50 stains.
That all fits the profile of expirated spatter almost perfectly.
Step 4: Mechanistic reasoning
Here’s the likely sequence:
1. The bullet entered from behind, damaging the heart area, aorta, and airway.
2. Blood flooded into the chest cavity and airway.
3. As the victim exhaled or coughed (possibly involuntarily), blood was expelled forward from the mouth and/or nose.
4. Those expelled droplets created a forward rectangular area of small stains — the expirated blood pattern.
If the gunshot spatter had produced these stains, you would expect them behind or around the wound site, near the line of fire, and in much higher numbers.
Conclusion
Observation: ~50 small stains
Interpretation: Too few for gunshot mist
Observation: Spread across 2.5 × 5 m
Interpretation: Broad, diffuse distribution typical of expirated spatter
Observation: Located in front of victim
Interpretation: Matches expirated, not back or forward gunshot spatter
Observation: Airway and aortic damage
Interpretation: Mechanism for blood entering and being expelled from airway
Observation: Close-range shot
Interpretation: Doesn’t explain stains in front unless expirated
Most consistent finding: Expirated blood spatter
Final answer:
The pattern you describe — small stains, limited number, found in front of the victim, after a gunshot that damaged the trachea and aorta — is most consistent with expirated spatter rather than gunshot spatter.

Det du och Chat GPT kort och koncist försöker säga är alltså att offret hostade till kraftigt på vägen ner mot marken, varpå de över 50 blodstänken på 2-3 meters radie uppstod?
Invändning:
Det är just det där med kroppspulsådern, att det omedelbart blir ett väldigt tryck, en massa blod sprutar ut innan kroppen ens nått marken, vilket vi såg exempelvis i det förfärliga dådet i USA nyligen.
