The Case of a Blood Stained Motorcycle Jacket

A blood stained jacket was found about 300 feet from where the sneakers were discovered. It had been cut along the bottom, then re hemmed with a sewing machine using white thread. An unusual marking on the back of the shoes was traced back to a wizer motor bike - meaning whoever owned the shoes also rode this make of motorcycle. Detectives sought to polygraph test every male student and school faculty member within the area. This would amount to a total of around one thousand 750 tests, making it the largest mass polygraph examination in united states history.
