Multiple local, county, and state law enforcement and investigating agencies in Maryland offer detailed reports on their websites regarding the number of crimes and murders in Maryland by year. In addition to local and state websites, the Federal Bureau of Investigation issues an annual Uniform Crime Report which details the types of crimes, their rates and statistics per year, and the general location where each crime is committed within every city, state, and county. Another great resource for researching homicide statistics or cold cases in each state is Project: Cold Case, which not only has a public cold case database, but also has a webpage that is dedicated to showing the number of unsolved homicides in every state in the United States from 1980-2019. According to this page, between 1980 and 2019, there were around 24,540 murders in Maryland, and as time passed, approximately 16,677 of those murders were solved, leaving law enforcement with roughly 7,863 unsolved murders in Maryland. As previously mentioned, Project: Cold Case also has a public database which contains the basic information for almost 25,000 cold cases across the United States.
