Just touching something would not give off DNA, it would give off fingerprints. You need saliva, blood, semen, or a good amount of skin cells to get DNA. With only a little of this, you could get mitochondrial DNA, which is less discriminating. But getting DNA evidence is not as easy as most people think

I guess if someone doesn't love you back, it isn't such a crime, But there's a fine, fine line between love, and a waste of time. ... And I don't have the time to waste on you anymore. I don't think you even know what you're looking for For my own sanity, I've got to close the door, And walk away...
