First, cast the shoeprint impression outside the shed door. Also dust the handle for fingerprints. Now you can go in.

Swab the top of the gas can to see what's in it. Up on the shelf are Ecuadorian bottles of wine - grab one with the gloves. There's a nail below the shelf with a thread on it - grab that too.

Back at the lab - the gas can held the same jet fuel. The nail held the same rag.

Separate out the prints. One set is Gray's, and the other belongs to a new guy - Stan Ginns, a drug dealer. Interesting!

The shoe prints are a size 11 1/2. Who could those belong to?
