Write A Forensic Report
Write a forensic report that separates evidence, conclusion, and limitations.
- Observation vs. inference: Forensic work starts by separating what was seen from what is concluded.
- Evidence identity: Labels, photos, and logs keep evidence tied to the right source.

Write a forensic report that separates evidence, conclusion, and limitations.
| Report section | What belongs there |
|---|---|
| Question | what was investigated |
| Evidence | photos, logs, test results |
| Conclusion | claim supported by evidence |
| Limitations | what is uncertain |
Use the report outline. Which sentence is a limitation?
Reviewed| Report section | What belongs there |
|---|---|
| Question | what was investigated |
| Evidence | photos, logs, test results |
| Conclusion | claim supported by evidence |
| Limitations | what is uncertain |
- A.Only one sample was tested
- B.The evidence bag was labeled A3
- C.The sample turned blue-black
- D.The question was about starch

Answer: A. Only one sample was tested
- Step 1: Define limitation: A limitation says what makes the claim weaker.
- Step 2: Apply sentence: Only one sample means limited evidence.
Why it's right: Only one sample was tested is a limitation.
- B: This is documentation evidence.
- C: This is evidence.
- D: This is the question context.

A report conclusion reads: "The blood on the table is Anna's, and whoever left it clearly panicked." Which phrase does the evidence not support?
Reviewed- A.That blood was found on the table at all
- B.That whoever left the blood panicked
- C.Both phrases, since a conclusion may not name a person
- D.That the blood on the table came from Anna
Show the worked solution ▾
Answer: B. That whoever left the blood panicked
- Step 1: Split the sentence: One phrase reports a laboratory match. One phrase reports a state of mind.
- Step 2: Ask what evidence exists for each: A DNA profile can support a match. No laboratory test reports panic.
Why it's right: A profile match is a result the lab can back. A claim about someone's emotional state has no test behind it, so it does not belong in a conclusion.
- A: The presence of blood is a recorded observation from the scene.
- C: Naming a person is allowed when a test supports it; the unsupported phrase is the one about panic.
- D: A DNA profile comparison is exactly the kind of finding a conclusion may rest on.
