The Case of Lois McArthur

A suicide note lays nearby a body that has been found. A closed case? It would seem so but did Lois McArthur really take her own life? Or does someone want the authorities to think she did?
Students analyze hair and fiber samples, test six simulated blood samples for type and compare fingerprints found at the scene to those of five suspects. They examine handwriting samples of the victim, the suspects, and the alleged suicide note.

Includes materials for 12 student groups, a teacher’s guide, and reproducible student instructions.
