I'm going to try one more time to appeal to your logic side.
I showed you how to google those cases where they tried and failed. BUT if they got away with it, then more than likely there are no articles about it, right? You went through the accelerated path to homicide detective so you must be top of your class, so I doubt you have any cases like this but you're aware that there are people out there that have gotten away with murder because there was just never enough to make a case, right? How many of those made the news? Because if there was no case, then there was no trial, and then there is no story, BUT there are many detectives and lawyers out there that know there's more to the story but just couldn't prove it.
