Plot summary
An investigation into the murder of a cop in a subway station leads Goren and Eames to believe he was blackmailing a pair of doctors; the voyeuristic Dr. Roger Stern ( James Urbaniak ) and oversexed exhibitionist Dr. Scott Borman ( Todd Stashwick ). Further investigation and evidence from an ex-girlfriend, Megan Colby ( Carrie Preston ), lead to an evidence that Stern has been infecting his former girlfriends with rare diseases. Goren plays on the doctors' obsessions to elicit their confessions.
