There have been 894 instances of mass shootings in the United States since the murder of 20 children and six of their teachers at a school in Connecticut in December 2012.
The incident was the deadliest mass shooting at a school in US history and the second deadliest mass shooting by a single person after the Virginia Tech massacre in 2007.
Speaking about the tragedy a few months later in March 2013, President Barack Obama said "shame on us" if they forget what happened and continue to block gun law reform.
But two and a half years later, this map suggests America has failed to learn lessons about gun crime.
The map shows the spread of attacks across the country since 1st January 2013- less than a month after Sandy Hook.
It includes the murder of two Virginian journalists, Alison Parker and Adam Ward, who were shot live on air while filming a live news report on Wednesday.
It also shows there have been two mass shootings since the attack - killing at least three people and seriously injuring at least five.
