Crazy for You

S3 E7: The detectives must piece together partial clues to lead them to the murderer of a husband-and-wife team of psychiatrists. Jane finds herself closer to the investigation than she realizes. Also, when the Boston Police Department hosts a seminar for Medical Examiners, one of the attendees (guest star Country singer CRAIG MORGAN), offers to help Jane and Maura on their case. Meanwhile, the Rizzolis have their hands full when they discover there may be a link to a pregnant stranger they've met.
