Study the room carefully. If you see an item that looks like a clue, click on it to add to your evidence bag, but choose carefully, as you can only take four items with you back to the lab.

If an item you've chosen implicates a suspect a picture of them will appear on the right of your screen. You can then click on their picture to read their statement.

Once you believe you have identified the murder suspect drag their face onto the handcuff icon to find out if you were correct.
