Q

MEASUREMENT TECHNIQUES (4)

A

Baseline Method
Rectangular Coordinate Method

Triangulation Method

Grid method

35
Q

Run a baseline from one fixed point to another, from which measurements are taken at right angles.

A

Baseline Method

36
Q

Works best for outside crime scenes

A

Baseline method

37
Q

Uses two adjacent walls as fixed points as distances are measured at right angles

A

Rectangular Coordinate Method

38
Q

Use 2 walls as baselines and measure to the object

A

Rectangular Coordinate Method

39
Q

This is the most common method best for interior crime scenes

A

Rectangular Coordinate Method

40
Q

Uses a protractor to measure the angle formed by two lines

A

Polar Coordinates Method (Compass point Method)

41
Q

Common in outdoor scenes uses straight-line measurements from two fixed objects to the evidence to create a triangle with evidence in the angle formed by two straight lines.

A

Triangulation Method

42
Q

Most accurate but most time consuming

A

Triangulation Method

43
Q

COLLECTION OF EVIDENCE
-Documentations

A

a. during collection
b. packaging
c. sealing
d. turn-over to Evidence Custodian

44
Q
  • the means sanctioned by the court of law, in ascertaining in a judicial proceeding, the truth respecting a matter of fact
A

EVIDENCE

45
Q

that which is legally submitted to a competent tribunal as a means of ascertaining the truth of any alleged matter of fact under investigation before it

anything which a suspect leaves at a crime scene or takes from the scene, or which may be otherwise connected with the crime

A

EVIDENCE

46
Q

Reasons Why Physical Evidence Should Be Discovered in Crime Scenes (6)

A
  • Physical evidence provides clues or leads upon which an investigator will base his investigation
  • Establish the identity of the persons involved.
  • Assist the investigator to destroy the alibi of the suspect.
  • Establish the fact of the felony & prove the commission thereof.
  • Disprove fabricated reports & set free the innocent person.
  • Aid the investigator to arrive at the appropriate offense or felony.
47
Q

CONCEPTS WITH REGARDS TO THE QUALITY AND USEFULNESS OF PHYSICAL EVIDENCE IN ESTABLISHING IDENTITY

A
  1. Individuality
  2. Class Characteristics
  3. A preponderance of such evidence
  4. Probability
  5. Rarity
  6. Theory of transfer
  7. Comparisons
48
Q
  • a combination of independent ovents wil occur is the product of individual probabilities. Thus. the probability of association with a particular situation may be very high when a number of separate factors are found ot correspond.
A

Probability

49
Q
  • the determination of whether or not an object or item should be collected as evidence will frequently rest on the following circumstances: it seems out of place; it is unusual for the item to be in a certain place; or the condition of the item or object indicates unusual change.
A

Rarity

50
Q
  • when two objects come into contact, there will frequently be a transfer of al amounts of materials from one to the other.
A

Theory of transfer

51
Q
  • the most definite point of comparison between object si an obvious physical match.
A

Comparisons

52
Q

WHAT ARE THE PRINCIPLES TO BE OBSERVED IN HANDLINGALLTYPESOF PHYSICAL EVIDENCE?

A
  1. The collected evidence should reach the laboratory as much as possible in same condition as when it was found.
  2. The quantity of collected specimen shall be adequate for purposes of forensic examination. Even with the best available equipment, good test results cannot be obtained from insufficient specimen.
  3. Submit a known or standard specimen for comparison purposes.
  4. Keep each specimen separate from others. Wrap and seal in individual packages when necessary.
  5. Mark or label each piece of evidence for positive identification.
  6. The chain of custody of evidence must be maintained. Account for evidence from the time it is collected until it is produced in court. Any breaking this chain of custody may make the material inadmissible in Court
53
Q

TYPES OF EVIDENCE THAT CAN BE LOCATED AT THE CRIME SCENE

A
  1. Physical Evidence
  2. BiologicalEvidence
  3. ImpressionEvidence
  4. TraceEvidence
  5. ElectronicEvidence
54
