What is the average murder clearance rate?

In the US, the homicide clearance rate has fallen from ~90% in the 1960s to approximately 50–55% in recent years. Property crime clearance rates are much lower — typically 15–20% for burglary and 13–15% for motor vehicle theft.

What does 'cleared by exceptional means' mean?

A case is cleared by exceptional means when police identify the offender but cannot make an arrest due to circumstances beyond police control, such as the suspect's death, prosecution declined, or victim's refusal to cooperate.
