The July 4 mass shooting at a parade in Highland Park, Illinois, which left at least seven people dead and dozens injured, came on the heels of several other devastating shootings around the country.
The FBI regularly chronicles active shooter incidents. Because there is no set definition of a mass shooting, the data can appear different depending on the source. In this gallery, we included shootings that took place primarily in public and in which the victims were overwhelmingly not related to the perpetrator.
Some of the shooters began their rampages at home and then moved into the public places. Some shooters moved from place to place, killing people along the way, and others killed all of their victims in one particular location.
These are some of the deadliest mass shootings in American history.
