Laboratory (Lab) #5
Once you've arrived at the laboratory, you will have to witness a short cut-scene with Sara. You will receive some new evidence from her.
New evidence: Security Camera Video
Before we'll deal with the security camera issue, you should consider using a DNA analyzer once again. This time you will have to compare Swab from Outside of Condom to Liz's DNA (you received it a few moments ago). Obviously you will be rewarded with a positive result.
Now you will have to listen to a short conversation between Nick and Grissom. Start off by using a computer. You will have to choose a new feature - Video/Image Enhance. Obviously you must place the Security Camera Video in the central field. Nick will suggest to play the tape before analyzing it. It's a good idea, so go ahead and press PLAY. After that, you will have to investigate it frame by frame. Start clicking on FRAME+. You will have to repeat this action several times. Check the screen, because that's the frame you have to analyze. Once it's on your screen, press the ENHANCE button. This will allow the computer to find something important. It's going to be a poncho of the passenger of the cab. It's almost identical to the one from the Fire Temple.
New evidence: Image of Poncho from Video
I'm sure that you won't be surprised by the fact that you have to return to the Fire Temple.
Fire Temple #4
As you've probably suspected, you will have to proceed towards the tent right away. Head on to the bed area. You shouldn't have any problems finding the poncho. It's still inside the chest. Click on it and choose Latex Gloves from your inventory.
New evidence: Hooded Poncho
This will also allow you to unlock a new interrogation warrant on Liz. Don't close this window, though. You will have to inspect the designated area (screen). Use an Adhesive Mount and click on a darker fragment.
New evidence: Singed Fibers from Poncho
Go back to the Lab.
You will have to use a comparison microscope. Start off by dragging the Singed Fibers from Poncho to the left window. You won't have to compare it to anything else. Just make sure that you have listened to what Nick has to say to you. Go back to Brass' Office.
Brass' Office #4
You will have to ask Brass to give you a new warrant:
- Can I get a warrant? -> Liz Sunderland? -> Can we get a Suspect Warrant for Liz Sunderland?
Wait for the Interrogation Room to be displayed on your screen. You will have to interrogate Liz:
- We think you killed Bob Castner.
- What time again was it that Bob kicked you out of the cab?
Ask Brass (by clicking on him; you won't have to go back to his office) to allow you to question Ed Danville again:
- I'd like to question Ed Danville again.
Here are the questions:
- We know you were intimate with Liz, the Fire Goddess...
- Maybe you helped Liz kill Bob Castner?
- You tore your jeans on the fence...
- Why were you at the foundry?
- Could be you and Liz smoked the cabby as a favor to Debra.
Once the conversation is over, head on to the Tribal Leader House.
Tribal Leader House #3
You won't have to pick up any additional items here. Just make sure that you've talked to Debra:
- Does this poncho belong to you?
- In the temple back room. Do you know how it got there?
- Is there anything else you can tell us?
- Any idea who took it?
- We'd like to have a DNA sample from you.
Thankfully, Debra will cooperate with you. As a result, you will receive a sample of her DNA.
New evidence: Debra's DNA
Head on to Brass' Office, because you will be able to fully interrogate Debra in the station.
