Most murders are not difficult to solve. People are usually killed by someone they know, there is usually abundant evidence and the police methods used to investigate this type of crime are highly effective. But what about the more difficult cases, where the investigation involves an unusual death, an unusual killer, or is complex or politically charged? In these cases, bringing the accused before the courts can take many years, even then, the outcome may be contentious or unresolved.
