S01.E02: The Hunt for the Runaway Killer - The Genetic Detective [V]

I'm really enjoying this series.  I know a thing or two about DNA testing, so I wonder what people who are less familiar with it think. 

I tried to start a thread for episode 3, but the site wouldn't let me do it. 

If you miss an episode, you can watch free on the ABC site apparently a week after the episode airs. (At least currently episodes 1 and 2 are available free, but for episode 3 they want you to sign in with your TV provider.)
