你马上会觉得自己真的在shithole国家。事实是：Over 600,000 individuals go missing in the United States every year.[1] Fortunately, many missing children and adults are quickly found, alive and well. However, tens of thousands of individuals remain missing for more than one year – what many agencies consider “cold cases”.

It is estimated that 4,400 unidentified bodies are recovered each year, with approximately 1,000 of those bodies remaining unidentified after one year.[2]
