Homicide and terrorism are the two chosen cases for this illustration.
There is voluminous amount of work that requires to be done with the witnesses, evidences, statements and items prior to the case being brought before the jury and the judge subsequent to the information of the original misdeed. A number of ethical considerations should be put into considerations from the establishment of a particular case say homicide. The exploration of particular cases should remain in the hands of law enforcement workers who are directly connected to the information and case concerning the suspect's true identity, the approach and procedure followed to retrieve information from the said suspect and the fact that neither coercion nor excessive force was employed so as to attain a confession etc (Schmalleger, 2006).

Draft should be prepared of the sight as to the site of evidence or body etc.
Process every information and tangible evidence that was gotten and follow through on it.
Prosecution problems that can arise when the case is presented for trial if the investigator was unethical
In case a case is presented for trial deficient of the ethical principle of the investigator, a number of prosecution problems may arise: if the whole or part of the terrorism or homicide inquiry is pushed or rushed through devoid of the whole thing being handled in a professional and thorough manner, a mistaken suspect might be held convict under sham pretenses or worse still the case in question might be thrown out of the court; a legal malpractice claim might be filed against the investigator, the unprofessional and improper handling of the relationship between the attorney and the client results to negligence claims which are not founded on the definite services given.
