I've Got a Secret - S4.E11

Lewis and Kellerman try to subdue a large man who's gone on a rampage. The large man is finally subdued and they find him digging up his mother. This case brings out some information about Meldrick's family, and he tries to see his brother, who doesn't want to see him. Kay tries to keep the identity of her new boyfriend a secret, mainly from John, which drives him crazy. Pembleton and Bayliss investigate the death of a man whose body is found in a car. Scheiner says he died from internal bleeding, not the gunshot wound to the groin he was treated for at an emergency room earlier that day. They discover that the doctor may have had a motive for doing a less than adequate job treating her patient.
