It does become evidence, and is held and used as such. A judge will determine if the money was collected in the commission of a crime (drug trafficking) and if he so determines, the money becomes property of the state's general fund. Contrary to the belief of some of the posters, the money is not divided out among the officers, or used as bonuses, or confiscated so the police dept can buy stuff. Get real, people....you don't really believe that, do you? Any proceeds that go to the local level do so at the largess of the state.
