The SleuthLab cast
Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.
-
Loop Impression evidence — fingerprints, shoeprints, toolmarks (class vs individual evidence) -
Fiber Trace evidence — fibers, hairs, paint, glass (Locard's exchange principle) -
Drop Chemical evidence — chromatography, pH, spectroscopy (test-don't-guess) -
Stroke Document analysis — handwriting, ink, paper (comparison methodology) -
Witness Biological + digital evidence — DNA + digital footprints (statistical-match, not certainty) -
Seal Chain of custody — bag it, label it, log every hand it passes through; a broken chain can't be trusted; otter with evidence bags + logbook -
Sketch Scene documentation — record the scene before anyone touches it; the scene only tells its story once; heron with a measuring notebook -
Tick Timeline reconstruction — put every event in order on the clock; the sequence is where the answer hides; mouse with a paper timeline -
Branch Alternative explanations — ask 'what else could explain this?' and test each branch before choosing; squirrel with a whiteboard of possibilities -
Account Testimony reliability — ask open questions and listen; memory is fragile and a confident witness isn't always correct; rabbit with a gentle notebook
