Wichita Eagle | 04/04/2005 | Still more answers to BTK questions: "Why was the name 'Anderson' in the 'Chapter 8' puzzle?

Maybe because the name 'Larry Anderson' also appeared on one of the fake IDs included in that package to KAKE. But if you include the three letters in front of that surname in the puzzle, it spells out 'Ian Anderson.' That's the name of the lead singer, songwriter and flautist of Jethro Tull. Was BTK a fan of the British band?"
