1. Describe Anthropometry and how it was used in criminal identification?
Anthropometry is the first method of criminal ID that was considered to be trustworthy. The
method of Anthropometry is based on the fact that every individual has exact measurements
that are unique to only them, and when all these measurements are added up it creates a
special formula specifically for that person. Bertillon the finder of this method came up with
the conclusion that when looking for a criminal only 4,191,304 to 1 share the same 11
measurements as that individual (Pg 10-11).
2. What was the first criminal case in which DNA was used? What was significant
about the case?
The use of DNA was discovered in 1968 but was not used until the Enderby case in 1983,
England. 15-year-old Lynda Mann was raped and murdered, but her case was left unsolved. 3
years later the same thing happened to 15-year-old Dawn Ashworth. Investigators compared
the DNA retrieved from both bodies and came to the conclusion that the same person killed
both teenage girls. Initially they arrested a 17-year-old, but his blood sample was not a
match. Since they had little to no DNA samples, they decided to collect samples from all the
men in the area aged 13 to 30. At the end, the murderer was found (Pg 14-15).
3. What is meant by a plain view seizure and what are the requirements for
conducting such a seizure by a law enforcement officer. Discuss some of the other

exceptions to the legal requirement of needing a warrant to conduct a search and
seizure.
A plain view seizure is as the name states if the contraband is in plain view than the
officer or investigator can legally seize the contraband. The requirements for conduction
such seizure would be that the officer would have to be lawfully present where they saw
the evidence and have a plausible cause to believe the item is illegal or evidence
pertaining of a crime. Now if said officer must go out of their way to invade a civilian’s
person property or privacy than it would not be considered a plain view seizure (Pg 38-
39).
4. Identify and discuss the skills and traits that make an investigator successful.
One of the most important skill that makes a great investigator is the ability to converse
will with all types of civilians, since most of collected information comes from the
people. Additionally, you must understand that any piece of information collected from
people whether it may be big or small is considered important. Another skill I believe to
be of very importance is to have the ability to gain the confidence of the people they
interact. Investigators also have to keep in mind that acting maliciously or going the
unethical way to get the case solved will not do you or anyone else involved any good.
(Pg 43-44)
5. What is the difference between inductive reasoning and deductive reasoning? Be
able to give an example of each.

Inductive reasoning uses specific details to come up with a conclusion while on the other
hand deductive reasoning uses observations and analysis to come up with a theory about
the crime. I believe a example of inductive reasoning would be, Ms.A , Ms.B , and Ms. C
were all vile middle age teachers who were recently murdered, therefore the next women
who will get killed must be a vile middle aged teacher. Now deductive reasing would be
that.all middle age teachers are vile, Ms.D is a middle age teacher so she must be vile and
the next one to be killed (Pg 44).
