Spoiler: Death Scene So this is scene, I'm in the window room of the gun shop marked with the blue circle. I snip a detective on the road shown with a blue circle as well. How is it that there was still DNA? Are the bullets thoroughly licked, then loaded to fire?
So DNA on kills don't actually follow physics of real life. It's more of just a tactic to help the Innocent team out, and give birth to the specialties of the Detective role. The time left on a body with DNA decreases as the distance increases. So if you shoot him from a far, the time for innos to get DNA would be shorter than it would be if you shot him point blank. It decays almost instantly if it's far enough.
