Is it Crime Busters?
I am trying to find a game that I used to play as a kid (late 80s early 90s). It had pictures of crime scenes and a scenario and you had to figure out what happened. You found the answer by looking through one of the red decoder strips. Someone told me once it was Crack the Case, but after looking at it I'm 99% sure that isn't it. Anyone have any clue what I'm talking about?
