Acknowledgements

This project originally began as a research blog, Sandy Hook Lighthouse, in 2013. The blog’s primary purpose was to collect evidence of the shooter’s online activities. During the years that it was active, a number of people wrote to contribute tips, or enlightened my thinking on this case, and this phenomenon. Others patiently gave feedback on drafts of this story, which was invaluable; thanks are due to Jonas Rand, CW Wade, Peter Langman, AG, Patro, Sabratha, Ashley, Dingo, Cole Scott, Carrie, Ryan, and JK.

Finally, there were a number of individuals who reached out to me over the years — and often contributed significantly to understanding the events that led to 12/14/2012 — but also declined to be named publicly. I remain grateful for their help, and will continue to honor their wishes.
