What is the indirect evidence?
¿La evidencia indirecta?
Indirect Evidence (Circumstantial): evidence that suggests what happened but does not directly prove that our suspect is guilty.
Examples: DNA evidence at a crime scene shows somebody was there but does not prove that they committed the crime. Like fingerprints and hair strands
Prueba indirecta: evidencia que sugiere lo sucedido, pero que no demuestra directamente que nuestro sospechoso sea culpable.
Ejemplos: Las pruebas de ADN en la escena del crimen indican que alguien estuvo allí, pero no demuestran que esa persona cometiera el delito. Tal es el caso de las huellas dactilares y los cabellos.

What is the difference between direct evidence and indirect evidence?
Direct evidence proves a fact directly against our suspect, while Indirect (Circumstantial) evidence provides clues that suggest what happened but does not, by itself, prove it.

Would a bloody fingerprint be considered
A. biological
B. physical evidence
C. both
C. BOTH

Why is individual evidence generally considered more powerful in a court of law than class evidence?
Individual evidence directly points to the presence of guilt of someone at a crime scene

Which of the two (Indirect or Direct Evidence) can be split into 2 categories?
What are the two categories?
Indirect can be split in PHYSICAL and BIOLOGICAL evidence.

PHYSICAL- Weapon |Fingerprints | Shoe prints | Clothing

Explain why fingerprints are classified as PHYSICAL EVIDENCE and not biological evidence
(The same rule applies to FOOTPRINTS and SHOEPRINTS)
Fingerprints are physical evidence because they are marks left on a surface, not body material like blood or saliva.

At a crime scene 500 gallons of red blood cells were found spilled on ever surface, every wall, every object, every wire, every cup of water, your mom.
Would the blood be considered Individual or Class evidence
Since they are red blood cells they are considered CLASS EVIDENCE as they lack a nucleus and your DNA and as such, can't be used to track who you are.

What are the 3 Factors that affect Locard's Exchange Principle?
Extent of the transfer if based on
Intensity of contact (How strong the contact is)
Duration of contact ( How long the contact last)
Nature of the materials (What material are touching)

Question: How can modern technology make direct evidence less trustworthy?
In your answer, include a piece of modern technology and an example of direct evidence.
AI can create fake videos, pictures, or recordings that look real, so direct evidence may not always be reliable.

You come across a absolutely strange crime science
The walls have been warped inwards beyond the points of logical euclidean geometry, the ceiling has been extended so far upwards that the atmospheric fog has consumed any way for you to indicate a ending, time has become a suggestion as there is no conceivable infinity in which you will ever reach the top. On the floor is a singular bloody crowbar bent in the shape of a smile
Is this item
A. biological
B. physical evidence
C. both
Crowbar=Physical
Blood=Biological
Together=Both

A fingerprint was found at a crime scene. The crimer investigator took the DNA and found it to match ONE specific person.
Is this Class or Individual Evidence? and Why?
INDIVIDUAL EVIDENCE
because the fingerprint can be linked to one specifc suspect.
500
Why is TRACE evidence considered INDIRECT evidence?
Because trace evidence gives cues about what happened, but does not directly prove our suspect.

What were the earliest animals to come onto land?
Early myriopods resembling centipedes/millipedes
Prehistoric giant scorpions are a acceptable answer :D
