Most cases are solved by DNA test? - answer False
-
,All types of real evidence has two things in
common
- They must be marked and formally introduced
into evidene and
- the attorney who wishes to introduce them must
lay a foundation to establish the admissibility if the
items in question - answer
Process of marking has 4 steps
- First, the item must be shown to opposing counsel
before testimony about it is introduced (give the
attorney the chance to see what is to be discussed
and form appropriate questions)
- Second, the side that tends to introduce the item
has the court cleark assign it a number or letter for
identificiation
- Third, the witness must be called to lay a
foundation necessary to show that each item is
admissible
- Last, a formal request is made to admit it into
evidence - answer
Crime Scene Evidence
, - All items that are admitted as exhibits must be
authenticated, which means shown to be genuine
- To authenticate evidence found at the crime
scene it is necessary to show that the item is the
same one described by the witness
- It needs to be in the same condition that it was in
at the same time it was found by the police unless
it was necessary to conduct laboratory tests on it
-No one should be allowed to try to clean up the
arean before the investigation is completed
because evidence could be destroyed - answer
Processing the Evidence at the Crime Scene
- The first step in laying the foundation for the
admission of crime scene evidence is to have
someone identify the object and testify about
where the item was found
- If the item has a serial number or some other of
identification it is easy process to identify
- However just describing it is not good because
there were more than one of these made
*Most common solution to this problem is to make
a mark usually the officers initial on the item at the
time it was collected.
