2. recognition - of not just what but where
- situation of items relative to each other
3. where to start consider paths of contamination from:
searching - perpetrator activity
- first responders
- emergency response
- look out for media interference
4. how do you search - lane/strip search
a crime scene? - line search
- circle/spiral search
- zone search
5. what are some canine units
other search tools? metal detectors
heavy machinery
thermal imaging
ground penetrating radar
6. search method is - indoor/outdoor
based on factors - size
such as: - urgency
- lighting available
- what is being searched for
- what evidence was already found
- concentration of material
- people available
,7. lane/strip search good for large areas
good for uneven terrain
8. line search limit must remain in a super straight line with everyone else as you move across
crime scene, at the same pace
9. circle/spiral search good for locating additional items associated to an existing piece of evidence
benefits typically done indoors - too diflcult to do outdoors
10. circle/spiral limits diflcult to stay in a perfect spiral path to ensure nothing is missed
11. zone search bene- good for where other patterns won't work - typically in a house divided by rooms
fits - used where scene is already broken up into zones

ted for analysis? - no probative value
, - an individual is already associated with the item
- item has previously been tested for body fluids or fingerprints
23. sequential pro- use of as many developmental techniques as necessary to process a piece of
cessing latent evidence, applying least invasive to most invasive
24. what are the sys- - severity of offense
tems in place - type of evidence
to prioritize sam- - probative value of evidence
ples/cases? - urgency/risks to public
25. what are the two high volume services and violent crime services

28. should you do pre- no
sumptive tests pri-
or to submitting
evidence to high
volume services?
29. how many items three pieces of evidence
