So in a case like this assuming the defendant is able to suppress any information used against him with respect to his location. Does it even matter for his case? The police now know who he is and assuming DNA evidence, rape test kit evidence, etc. come back and implicate him won't he still be found guilty? Or is all of that suppressed because the police wouldn't have found him otherwise without violating the 4th amendment?
Edit: Made my first question more specific
