Location of the deadliest shootout in US criminal history

The Young Brothers Massacre (sometimes referred to as the Brookline Shootout) was a gun battle that occurred outside of Brookline, Missouri on the afternoon of January 2, 1932. It resulted in the deaths of six law enforcement officers, making it the worst single killing of U.S. police officers in the 20th century. The event is little known of outside of the Ozarks region of Missouri where it occurred, and even books dealing with the “Public Enemy Era” of the 1930s rarely mention it. This may be due to the geographical and cultural isolation of the Ozarks at that time.
