evidence and investigation Flashcards
what are the seven ways of finding out a investigation
- fingerprints
- footprints
- fabric
- handwriting
- ink
- tire prints
- soil
what things should you look at when classifying footprints
size pattern,depth,distance between, wear,weight,height,type of shoe (ex.heels runners)
what things should you look at while classifying tire prints
treat pattern,areas worn down, depth
what things should you look for when classifying soil samples
colour, texture, odour, size, mixture of materials
what things should you look at while analyzing the ink
different colours
what thing should you look at while analyzing handwriting
slant/straight, space between letters and words,
handwriting printing, dotted “I”s and slanted “t”s letters connected loops
what things should you look at when comparing samples of fabric
colour, texture, pattern, reaction to flame, reaction to chemicals
what things should you look at when classifying fingerprints
loop, whorl, arch, composite, ridge ending
what is the meaning of observation
are information gathered through our senses see, and smell
what is inferences
are a conclusion about something based on an observation
what is the meaning of classify
means to arrange thing into groups according to similar quality
what is the meaning of evidence
is any bit of information, physical marking or objects that give people a reason to believe something
what are the four common types of evidence
- fingerprints-
- tire tracks-
- soil samples-
- handwriting samples
how are fingerprints made
left by tiny rides of your finger tip. These markings are left by dust or other particles on the oil of your skin
what is a arch fingerprint
goes from one side of your finger to the other
what is whorl fingerprint
has a circle in the middle
what is a loop fingerprint
begin on one side of your finger then becomes into a whorl
what is a composite fingerprint
all of the fingerprint put together
what is heterogeneous mixture
made up of than one substance like dirt, soil, twigs
what is graphology
the study of the letter shape in handwriting
what is a island
a very short ridge in the print pattern is not connected to any other ridge, much like an island floating by itself
what is a ridge ending
a ridge ends
what is a lake
a ridge in a shape of a circle
what is a bifurcation
1 ridge splits to a form 2 ridges and then rejoin one ridge again, forming a shape like a lake
