The kids loved it! Does anyone know who suspect 1 and 3 are? They're the only two I don't recognize...

You would eliminate the suspects with the MOST money because they are least financially motivated to have committed the crime since they have no need for more money. Therefore, suspects with the LEAST money would actually be more financially motivated to commit the crime since they had such a large need for money.

Thank you for sharing. My sixth graders really invested time to solve these problems. I used this as the evaluation for our unit.
