their original suspect, dale bradley, was now a suspect in yet another murder investigation, they decided to look once again at the evidence. and this time, on bryan ruff's boot, the one they found in the mountains near his burial site, they spotted something, some kind of scuff mark on the bottom of the boot that looked like reddish orange paint. >> when i saw that swatch of paint, it just flashed back to me that that was the same color of paint on dale bradley's car. and i got excited and i kind of got a little bit of butterflies and i thought, i got him. >> forensic scientist bill schneck examined this paint with a stereomicroscope. >> and i noticed it was a smear, it wasn't like paint chips on the boot, it was smeared into the leather on the bottom of the boot. there was tremendous force to get that paint smear on his boot.
