Ms. Josita's students walked into room 147 and discovered a "crime scene" in the classroom! A team of specialists was dispatched to the scene. The investigative team sprang into action. School Resource Officer Lee informed the investigative team that he had just engaged in a course on DNA evidence and could assist them in solving the crime. He and the team members worked together to examine each piece of evidence and discussed how DNA is different in all people with the exception of identical twins, who share basically the same DNA.
After ruling out several suspects from the crime, the investigative team concluded that the evidence matched only ONE PERSON on Rougon's campus. With DNA proof, the crime was solved! Mr. Johnigan was detained in room 147 and enjoyed sharing cookies and juice with the investigative team.
