What should an officer do if they suspect a crime has been committed but no evidence was found at the scene?

When an officer suspects that a crime has occurred but does not find any evidence at the scene, it is essential for them to perform further investigation to gather additional evidence. This approach aligns with the principles of proper law enforcement practices, where the responsibility of the officer includes pursuing all viable leads and employing investigative techniques that may reveal new information or evidence related to the crime.

Conducting further investigation can involve various actions, such as interviewing witnesses, checking surveillance footage, consulting with specialized units, or following up on any leads that may become available. This proactive strategy not only helps to build a stronger case but also demonstrates diligence and commitment to uncovering the truth behind the suspected crime.

The other responses either suggest abandoning the investigation prematurely or taking actions that may not effectively address the situation at hand, which could lead to missed opportunities for evidence that could be critical in resolving the case.
