Why? Adam Lanza was by all accounts reclusive and anti-social to an extreme. Why is it so unbelievable that he would not have left a big social presence online foot print? Sure, he was supposedly big into playing video games but not all games or players use multi-player options.
FWIW, I know a good number of people who do not use personal email accounts, don’t use Facebook or Twitter, etc. even some who do not even have PC’s at home. I work in HR and my employer has for the last two years required all employees to make their annual open enrollment benefit elections on line through our self service portal. But being a manufacturing company not all our employee’s have work computers and work emails. And I was surprised to learn that a number of these folks didn’t have PC’s at home and so we had to provide them with access to a PC at work, a temporary email account and basically hand hold them through the process as they were pretty much computer illiterate. These folks must have a zero online foot print but the absence of such is not evidence of their trying to hide something.
That Lanza tried to destroy his PC does not preclude the possibility that he had no on-line foot print. Busting up my hard drive wouldn’t destroy or erase my online footprint BTW.
You’ve got an interesting footprint here at FR yourself.
