As can be expected, the number of murders in Hawaii by year consistently changes. You can find statistics regarding crime data for Hawaii on multiple law enforcement agencies’ websites, both federal and local, which usually offer crime reports and statistics on their websites. Additionally, the Federal Bureau of Investigation (FBI) releases a Uniform Crime Report every year which shows, in detail, the crimes, crime rates, and the various locations of crimes that occur in every state as well as most counties and big cities in the United States.
According to Project: Cold Case, there are around 710 unsolved murders in Hawaii, which date from 1980-2019. Looking further into this, the same page on Project: Cold Case’s website shows us that from 1965-2019, there were around 2,073 unsolved murders in Hawaii. Over the years, roughly 1,363 of those murders were solved, leaving around 710 unsolved murders in Hawaii. We can expect that this number will only decline as time passes, but with the rising number of cold cases in the United States, it is unclear how drastically the number of unsolved murders in Hawaii will change over time.
