Analyze histology evidence
Fri, Sep 25, 2026 · Week 5 · Principles of Biomedical Technology (Principles of Biomedical Science)
Today's goal: Interpret tissue and heart observations with a CER and evaluate identification limits.
What a finished product looks like
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
Claim: The latent print lifted from the scene could indicate that this individual touched the surface before the incident.\nEvidence: Compared to a known reference print taken directly from the individual, the latent print showed the same pattern of ridge endings and bifurcations in the same relative positions, which are the features examiners use to match prints.\nReasoning: Identification is based on agreement between an unknown sample and a known reference, so the side-by-side comparison is what makes the matching ridge features meaningful. A shared arrangement of ridge endings and bifurcations is consistent with both prints coming from the same finger.\nLimitation: A partial or smudged latent print cannot confirm identity on its own; it must be combined with the quality of the reference print, the number of matching features, and other case evidence before a firm conclusion is reached.
Also due today: Upload your CER and annotated notebook page to the tracker by end of class.
