My question involves police conduct in the State of: California
I have three questions concerning personpower (see how PC I am) utilization with regard to murder investigations:
1: If a murder is committed in circumstances where no DNA or other clue is found at the scene of the crime, no witnesses are found after two weeks' trying, and no other leads exist, then (accepting that a murder case is never closed) for how long do the police persist with their inquiries if such inquires continue to produce no useful results?
2: Is there a general rule for how long an unproductive murder investigation may be actively pursued and, if so, what is it?
3: Is a record kept of murder (and other serious) cases that have to be 'abandoned' because of lack of resources and is that published?
