Impressions evidence

What are "Patent" or visible impressions?

• 3-D imprints left in a soft substance

• 2-D impressions that are visible to the unaided eye

• Impressions hidden to the eye but can be made visible using development techniques

• Impressions that are easily lost and must be documented right away with casting

What are "Latent" impressions?

• 3-D imprints left in a soft substance

• 2-D impressions that are visible to the unaided eye

• Impressions hidden to the eye but can be made visible using development techniques

• Impressions that are easily lost and must be documented right away with casting

• Photography

• Inking

• Dusting

• Casting

This type of evidence is created when one object is pressed against another material with force.

• class

• individual

• amorphous

Individual characteristics are unique identifiers observed only on an individual’s footwear or tire tread. Which of the following is an accurate list of individual characteristics?

• Brand, scratches, debris, and wear patterns

• Size, scratches, debris, and wear patterns

A tire track is left sunk into the mud.  What type of impression is this?

• Patent
• Latent
• Plastic
• Lasting

Shoe and tire marks impressed into soft earth can be best preserved by: 

• photographing and casting with dental stone
• photographing and then use of the electrostatic lifting technique.
• It is not possible to accurately preserve such markings
• dusting with powder

Why should an investigator not try to put the tool into the tool mark at the crime scene

• it will destroy the toolmark evidence that is there
• it will leave new evidence behind covering up the original
• contamination of the evidence
• all of these
