Using Cyanoacrlate ("super glue") fuming, MBD dye, and black powder on the knife collected at the crime scene and Cyanoacrylate fuming, ARDROX dye stain, and black powder on both firearms, the Evidence Processing Unit developed latent prints on all three items.

Afterwards, the Evidence Processing Unit swabbed the knife and firearms and took cuttings of the cigarette butts to allow the Biology unit to perform DNA testing.
