About how many cases have been solved using CODIS? - ANSWER-Around 500,000
Around how many wrongfully convicted people have been exonerated using DNA
evidence? - ANSWER-Around 300
Before DNA what was used? - ANSWER-Blood typing and enzyme/protein tests.
Neither of which are identification tools.
Correctly order the crime scene process from the first thing that you would do to the
last: record and collect physical evidence, secure and protect the scene, conduct final
survey, and photograph the scene. - ANSWER-1. Secure and protect the scene 2.
Photograph the scene 3. Record and collect physical evidence 4. Conduct the final
survey
Define latent - ANSWER-hidden
Describe the 1st case to use DNA - ANSWER-2 girls were raped and murdered. 4,000
men gave DNA samples, but one ended up coming forward to state that he had given
DNA on the behalf of someone else. This man was Colin Pitchfork, and he was
eventually found to be the killer.
Difference between Daubert and Kumho Supreme Court Case? - ANSWER-Kumho
involved manufacturing
Do all states have laws that require the collection of arrestee DNA? - ANSWER-No

Importance of Daubert Supreme Court Case? - ANSWER-Evidence must be validated,
peer reviewed, have a standard, have a known error rate, and be widely accepted
Importance of Frye Supreme Court Case? - ANSWER-General acceptance of forensic
evidence
What are some evidence collection techniques? - ANSWER-Scraping and forensic
vacuum
What are some forensic specialties? - ANSWER-Forensic Anthropology, Forensic

What are the 6 positions on a crime scene team? - ANSWER-Team leader,
photographer, the sketch preparer, evidence custodian, evidence recovery personnel,
and (possibly) specialist(s).
What are the most important identification techniques that we've discussed? -
ANSWER-Nuclear DNA and Fingerprints
What disciplines are associated with biological evidence? - ANSWER-DNA and
serology
What disciplines are associated with chemical evidence? - ANSWER-Explosives, solid,
liquid, gas, and toxicology
What disciplines are associated with impression evidence? - ANSWER-Fingerprints,
shoe prints, tire tracks, firearms, tools, etc.
What disciplines are associated with trace evidence? - ANSWER-Small items, fibers,

What do evidence recovery personnel do? - ANSWER-Locates and collects evidence,
aids in significant evidence photos, initial and date evidence, and they turn the evidence
into the evidence custodian.
What does CODIS stand for? - ANSWER-Combined DNA Index System
What does TEDAC do? - ANSWER-They take previous explosive devices and compare
them to current explosives to help them solve a case
What does the evidence custodian do? - ANSWER-Prepares evidence log, records and
receives evidence, coordinate evidence packaging and preservation, and has a
