Investigators have arrived at a crime scene and are ready to search for evidence. What needs to happen next? A
They should ask a judge for a search warrant to be able to explore.
B
They should only search for evidence at the primary crime scene.
C
They should map out a grid to systematically look for evidence.
D
They should only search for evidence if a case looks complicated.

C . They should map out a grid to systematically look for evidence.

Explanation:

As a crime has been committed, the investigators do not need a search warrant so there is no need to ask a Judge for one so option A is incorrect.

It is best if evidence is searched for in different locations not just the primary scene so option B is incorrect.

Setting up a grip to enable the systematic analysis of evidence is their most likely course of action so option C is correct.

Even if the case is not complicated, evidence still needs to be searched for so option D is wrong.
