Winged elephant hunting

The plague of other serial killers is the "repeated pattern". Some kill blondes, drawing attention to the pattern, some choose old people or children. The pattern is what allows the police to link crimes and monitor targets. As for me, I have no pattern, no preferred weapon, no specific location, and no clear motive. I am the one who will subject the world to the power of killing and pain, the power of the sacred, denied instinct.. the power of the perfect crime.But I still dream of something more; the perfect crime!! When can I achieve it without intervening or risking myself?
