Which of the following is a best practice for handling unsolved crimes?

Monitoring other crimes with similar modus operandi is a best practice for handling unsolved crimes because it allows law enforcement to identify patterns that could provide valuable insights into the crime in question. By understanding how the perpetrator operates, investigators can formulate more effective strategies to track down suspects and potentially connect multiple unsolved crimes. This approach not only helps in solving the current case but can also lead to breakthroughs in others, improving overall crime-solving rates.

Furthermore, continuously analyzing and comparing the patterns of similar crimes fosters collaboration and communication with neighboring jurisdictions, which may also be experiencing similar issues. This collaborative effort can lead to tips, shared resources, and a more comprehensive understanding of criminal behavior, ultimately enhancing the chances of solving the cases.
