Exam 3: Physical Evidence

The computerized database used to store DNA information is:

Match the word in Column 1 to its definition in Column 2. Each answer can only be used once. A)Database containing shoe prints B)Properties of evidence that can be attributed to a common source with an extremely high degree of certainty C)The process of determining a substance's physical or chemical identity D)The process for developing DNA profiles from a buccal swab in 90 minutes or less E)Properties of evidence that can be associated only with a group and never with a single source F)The process of ascertaining whether two or more objects have a common origin G)Database containing fingerprints H)Database containing ballistics information I)Database containing DNA profiles J)Formula for determining how frequently a certain combination of characteristics occurs in a population. -Class characteristics

The "jigsaw fit" of known and questioned fragments demonstrates common origin when a match is made.

As the number of objects linking an individual to a crime scene increases, so does the likelihood of that individual's involvement with the crime.

The two methods used by forensic scientists when examining physical evidence are identification and ________.

Evidence with individual characteristics can lead to a determination of common origin (single source). Which type of evidence CANNOT yield such results?

The PDQ is maintained by the:

What are three reasons why it is not possible to define a simple analytical scheme that can be applied to all types of evidence?

Which of the following is a national fingerprint and criminal history system maintained by the FBI and launched in 1999?

Determining that an explosive mixture contains dynamite is an example of the process of:

If the laboratory can piece broken glass from a window or headlight together, then the evidence has ________ characteristics.

Forensic databases are maintained for all of the following EXCEPT:

Most items of physical evidence retrieved at crime scenes can be linked definitively to a single person or object.

The first step in ________ is determining which properties from the suspect and the standard/reference specimen to compare.

A single-layer paint chip can normally be expected to have ________ characteristics.

To permit a positive identification, testing procedures must be sufficient to exclude all other substances.

It is a duty of the forensic scientist to draw a conclusion about the origins of the specimens.

Which database contains chemical and color information pertaining to original automotive paints?
