Melody Cheever: We learned so much at CSI camp. Dr. Lamar really makes science fun! He's going to watch the Youngs' security video with us. I hope he can give us some good advice about solving this case.

Dr. Lamar: What we have here is a classic example of Criminalus stupidus in its natural habitat (laughing, while pointing at the video on computer or television screen in front of him).

Melody Cheever: Yeah, we’re lucky to have this video.

Dr. Lamar: Did you see where he just stepped? (he rewinds the video and stops it)?

Melody Cheever: Yeah, it looks like in the flower bed.

Dr. Lamar: How is this different from the other places he was walking?

Melody Cheever: It’s the only area where there's soft dirt.

Dr. Lamar: Which means?

Melody Cheever: That he probably left his footprint there.

Dr. Lamar: Precisely!

Melody Cheever: I hope we can make an imprint if he did.

Dr. Lamar: When you go back, keep an eye out for any other potential evidence. Heck, if you find a piece of gum he chewed, we could try and extract the DNA. I have a friend in the genetics department who owes me a favor.

Melody Cheever: Thank you so much. We appreciate it!

Dr. Lamar: No problem. I’m always up to help solve a mystery.
