02.08.16 Catalyst What pieces of evidence allowed Dupin to solve The Murders in the Rue Morgue? Objective - I will compare class and individual evidence.

The week…

Individual v. Class Evidence notes & application

Individual Evidence Links victim, suspect, and crime scene Looking to establish the evidence triangle Victim suspect crime scene

Individual Evidence Examples: Fingerprints, DNA Matching torn materials or paint chips Striations on a bullet Audio recording, handwriting

Class Evidence Only linked to a group of persons or things Doesn’t establish positive proof; considered circumstantial The more, the better: “probable cause,” “weight of evidence,” “beyond a reasonable doubt” Statistics are often used to show probability of an event occurring

Class Evidence Examples: Blood types Gun shot residue Types of shoes

As we watch… Make a list of Class and Individual Evidence.. Be prepared to discuss your list. Forensic Files: Blanket of Evidence

Murders in the Rue Morgue Work with your table partner to annotate the text. Mark the two types of evidence Underline class evidence Circle individual evidence

09.10.15 Catalyst What three things must be present for something to be considered individual evidence? Name two pieces of evidence from the Poe short story. Objective – I will differentiate between class and individual evidence. Victim suspect crime scene

Today… Hearing update Rue Morgue – evidence types! Classify your shoes!

Catalyst 02.10.16 Give two things that make your shoes unique.

Today… Serial Episode 4

As you listen… Keep track of Jay’s story. How does it match with what we already know? What is confusing to you about his statement?

02.11.16 Catalyst Define circumstantial & give an example. I will compare direct and circumstantial evidence.

Today… Notes Wrap up characterizing…

Direct and Circumstantial Evidence

Evidence Direct Circumstantial Biological Physical Class Individual Class Individual

Direct Evidence Testimonials Eye witnesses and other witnesses Confessions No opinions allowed (hearsay)

Circumstantial Evidence Indirect evidence that is used to imply a fact, but does not directly prove it. Example: finding a suspect’s gun at the crime scene implies that they were there, but does not prove it. Can be physical or biological.

Trace Evidence – Locard’s Exchange Principle Whenever two people come into contact with each other, a physical transfer occurs. Hair, fibers, pollen, makeup, skin cells, etc. Intensity and duration of contact determines HOW MUCH is transferred.

Physical Evidence Fingerprints Tire, shoe, tool impressions Fibers Bullets, casings, firearms **Often Class Evidence

Biological Evidence Body fluids Hair Plant parts Natural fibers **often individual evidence

Evidence Direct Circumstantial Biological Physical Class Individual Class Individual
