Ranking factors for difficult crime

Nature of the crime

The type of crime committed plays a significant role in its level of difficulty to investigate. For instance, cybercrimes and financial crimes are often more challenging to investigate than theft or assault, as they involve sophisticated techniques and technology.
Evidence available

A crime with minimal or no evidence left behind is much more difficult to investigate. This may include things like a lack of witnesses, minimal physical evidence, or digital evidence that has been destroyed or encrypted.
Skill level of the perpetrator

A criminal who is knowledgeable in evading law enforcement or covering their tracks will be more challenging to apprehend. This may involve using counter-surveillance techniques, using encrypted communication channels, or having a network of accomplices to help them.
Jurisdictional issues

Some crimes may cross multiple jurisdictions, making it more challenging to investigate and coordinate efforts between different law enforcement agencies. This can also involve international collaboration and dealing with diverse legal systems.
Time elapsed since the crime

The more time that passes since the crime was committed, the more difficult it can be to investigate. Witnesses may forget details, evidence may degrade or be destroyed, and perpetrators may no longer be in the same location.
Resource constraints

Investigating certain crimes might require specialized equipment, expertise, or personnel which may not be readily available. This can slow down the investigation process and make it harder to identify and apprehend the perpetrator.
Complexity of the crime

Some crimes, like organized crime or terrorism, involve complex networks of people and activities. Investigating and dismantling these networks can be a significant challenge for law enforcement.
Legal constraints

Law enforcement agencies must operate within the confines of the law, which may sometimes limit the investigative techniques and strategies that can be used. This can make it more difficult to uncover evidence or apprehend a suspect.
Public perceptions and media coverage

High-profile crimes often receive significant media attention, which can influence public opinion and pressure law enforcement to quickly solve the case. This may sometimes lead to mistakes and shortcuts in the investigation process.
Cooperation with other agencies and organizations

In some cases, solving a crime may require assistance from other law enforcement agencies, businesses or non-governmental organizations. The level of cooperation and support from these entities can have a significant impact on the success of the investigation.
