  • The partial fingermark corresponds to the fingerprint taken from suspect B - Larry Lightfinger.

  • Why? Because the overlayed partial mark corresponds with the control fingerprint at 6 points (4 ridge endings + 2 bifurcations) and has precisely the same ridge spacing.

  • No similar correspondence is found with the fingerprints taken from the other two suspects.
