Try Crime Scene Lab free in your browser, with nothing to install and no account. Work a crime scene the way a forensics class does. Photograph the room, set the markers, bag the evidence the right way, powder the glass and lift the prints, swab the drops and take the note to the lab. Then classify and compare the fingerprints, turn each bloodstain's shape into its angle of impact and run the strings, run the inks on a chromatography strip, and build the case: claims in your own words with the evidence attached. Four suspects, one invented break-in, no body.
