NOTE TO READER Over the past two months, this series has documented, through Adam Lanza’s own recorded words, an ideology that developed in plain sight — anti-natalist, anti-cultural, and explicitly suicidal — more than a year before the shooting at Sandy Hook Elementary School. We have confirmed through law enforcement sources that recordings like these were known to federal authorities prior to December 14, 2012. The FBI visited the Lanza home before the shooting.
