Techniques of Observations.
a. Observing Persons.
Observe persons either for the purpose of being able
to describe them or to identify them from descriptions made by others.
observations should proceed as follows:
(1) First, general traits, such as sex, race, color of skin, height, build,
weight, and age.
(2) Second, specific traits, such as color of hair and eyes, shape of head
and face, distinguishing marks and scars, mannerisms, and habits.
(3) Third, changeable features at time of observation such as clothing
worn, use of cosmetics and others, such as hair styling.
When attempting to identify a person from a description, this pattern may be
modified or even reversed, especially if the person sought has some very noticeable
feature; for example, a man with a limp or a very tall woman. After first noting
this, further observation such as height, weight and age and additional
characteristics may then complete the identification as the person being sought.
b. Observing Objects. When observing physical objects for later description
or in the attempt to locate a previously described object, follow a pattern of
proceeding from general to specific. This should proceed as follows:
(1) General type of the item, including size and color.
(2) Specific distinguishing

(3) Make and model designation, when applicable.

piece of luggage.
(5) Identifying number(s), marking(s), or label(s), when present.
c. Observing Places.
Usually, detailed observations of places and locales
are made to mark the exact scene of an incident of crime, or detect relevant
evidence. In addition, the purpose may be to relate to an incident or crime such
information as has been obtained from witnesses as the result of their observation
of persons, objects, or events.
The basic pattern of observing places may vary
depending upon whether the place is in the open or outside a building or structure.
Most outdoor areas will either contain or be near natural
or manmade landmarks that may be used to pinpoint the location.
