After looking at the kidnap poster and a handwritten note from kidnapper, the girls looked shocked, wondering if all of this is real? Some of them suspected the teachers were playing an “April fool” prank on them.

Their excitement and enthusiasm reached its peak when they got to know that they are going to find out who the kidnapper is with the help of forensic science!

In a couple of lessons prior to this one, students learnt about forensic science and its importance in the field of crime investigation. Understanding fingerprinting patterns and paper chromatography were the key topics covered while teaching forensics. An important evidence of the crime was the fingerprints obtained from the crime scene. A handwritten note was the second evidence. Students were asked to think- pair- share about the method to be used to find out who the kidnapper was.

This case study was to help students understand the real life application of forensic science. Identifying fingerprints and performing paper chromatography to get the ink graph were the two methods suggested by students to find the kidnapper.

The class was divided into teams of four. Each team was tasked with finding out who the kidnapper was. Some of the students were sent to get the fingerprint samples of the suspects, Vandana, Tanushree and Noopura.  Also, students asked the suspects to give their pen samples for the chromatography test. Chromatography was performed to verify the ink samples which in turn tells you if the suspect’s pen is the same as that of the kidnapper.

With a lot of hard work, dedication and the application of forensics, students were successful in finding out who the kidnapper was. One of the suspect’s fingerprints matched with the fingerprints found on the crime scene. The chromatography result of the pen of the same suspect matched with that of the kidnapper. And this is how our little investigating officers solved a complicated case to rescue Urvashi.

Any guesses of who the kidnapper was? 😉
