Your first real mission on your own! You have Sara with you as you head out to the home of Jason Gray. Turns out Jason is a homeowner that has a home office. He was out running and when he came back, he found his home office was on fire. He put it out with a fire extinguisher but his computer has been toasted.

First, investigate the scene. By the desk you see glass. Zoom in and grab it with your gloves. Near the glass you also see a wood shard. Flouresce it and you're told Greg will like this one. Grab it with your gloves too.

Look up at the picture and "sniff" above it. You get some good fumes there.

The desk phone has a redial button. When you hit it, you get a "Yeah, leave a message" gruff guy's voice. You can't print the phone or anything.

The paper on the left of the phone should be sprayed with nihydrin to get prints. There's glass left of the window - you can only look at it to see that glass fell on the floor here, meaning the window was probably broken from outside.

Now out to the porch. Under the window you see glass - hmmmm, so maybe the glass was broken from inside? Tweeze some to get it. Also there's a kneeprint here - make a cast of it.

Back inside. Look behind the desk (you have to click to the left of it). You find a lighter beneath the desk and also some rags. Hmmmmm. Take both!
