Dylan Klebold and narcissistic

Omg does anyone remember this post back in like 2017 when tcc tumblr was at its highest of a post talking about Dylan Klebold possibly having covert narcissism? I’ve been looking for it for ages but I think it got nuked when tumblr took down a ton of true crime blogs. im probs gonna add unto this with my own theories later on but it would help a lot of any of u knew what im referring to!!!
