The NorCal library shooter wrote “Natural Selection” in black marker on his white T-shirt in a bid to mimic the Columbine High School shooters, officials said Tuesday. Bradley Scott Sayer, 18, allegedly shot and killed two people at a Butte County Library wearing the top, which cops said represented his obsession with the massacre. Columbine shooter Eric Harris wore a similar shirt as he committed an atrocity at his Colorado high school in 1999.
