Imagine the panic of discovering that $20,000 is missing from your checking account! When Alyson Marie Combs discovers her bank account has been emptied by someone forging her signature on a check, she is determined to work with law enforcement to find the culprit. Investigators gathered six different types of pens from the bank that may have been used to forge the signature. Students act as forensic scientists by analyzing the components of each type of ink using radial chromatography.
