Except in rush jobs for life-and-death matters, I think it normally takes a lot longer than 20 minutes for forensic lab reports to arrive. The cops are probably looking at a wait on the order of days, weeks, or even months. Twenty minutes probably isn't even enough time for the cops themselves to write up and submit the lab request and evidence.
