The FBI revealed that no murders occurred in Newtown.

http://www.snopes.com/info/news/sandyhoax.asp:   The FBI has revealed that no murders occurred in Newtown, Connecticut in 2012, inadvertently admitting that the Sandy Hook massacre was an elaborate hoax.

Of course, had the Newtown, Connecticut, school shooting been staged deliberately to separate Americans from their guns, one would expect the FBI to be complicit. Should the statistics for crime in Newtown inadvertently reveal a conspiracy of heretofore unimaginable scope, that agency need only explain its oversight as a clerical error, which has not happened.

So it’s a little hard to see how the FBI might have missed this. Looking in the actual UCR reveals the answer

As it turns out, a record keeping anomaly of sorts is at the root of the FBI report’s dissonant statistics for the Sandy Hook massacre. If you followed news of the incident at the time, you may recall that Connecticut State Police (not local city or town police) managed the crime scene in the hours, days, and weeks after the event in Newtown. Accordingly, the Sandy Hook Elementary victims were included in Connecticut’s statewide records, but they were not tallied as crimes of any description in Newtown in 2012. Rather, the deaths were classified under “State Police Misc.” in separate records.
