Body of Proof Episode 2.20 Mind Games

18-year-old Niki Shumaker downs multiple shots before laying kisses on a multitude of guys in a college bar. A short time later, she's found dead in an alley. The lip-locks were all part of Niki's attempt to pledge a sorority. Jack Gordon is a student who caught a kiss from Niki the night she was killed. The guy is described as stalker material. In other news, a disturbing x-ray motivates Megan to cut open the victim's skull. What she finds (or doesn't find) is truly disturbing. Someone has removed Niki Shumaker's brain.

Megan's seen something like this before. It was three years ago on her very first case. A serial killer named Wilson Polley is currently serving a life sentence, so the original suspect in the killings is now back in the picture as a possible copycat killer. Daniel Grubstick wrote a tell-all book to clear his name. He knows all about Polley's M.O. He also recognizes Niki Shumaker as Niki Marshall, the daughter of Wilson Polley's last victim.

Wilson Polley has an online cult following which leads the team to believe the copycat could be part of his posse. The guy blames Megan for putting him behind bars. He claims he's innocent. Being locked up has led his daughter to believe that he's truly evil. Still, he'll help Megan out by giving her some letters from his fans. All he wants from her is an apology once he's proven innocent. Yeah, good luck with that, Wilson.

Gordon Jackson happens to be part of Wilson Polley's posse. He claims he tried to protect Niki once he realized her true identity. He was completely hung up on her to the point where he cut off some of her hair when she kissed him. But Gordon swears he didn't kill her. Lab tests suggest that Niki's killer is also the person who killed the three other victims. Since Wilson Polley was locked up when this latest victim was murdered, there's a good chance he really is innocent. Megan has a different theory.

Megan believes Wilson Polley convinced Gordon Jackson to kill with his old brain hook so he could obtain a get-out-of-jail free card. The guy knows how to get inside a person's head. He even does so with Megan. As for the case, an Egyptian embalming hook is found at Daniel Grubstick's place though a partial print on it leads them to Wilson Polley's daughter. When the imprisoned man learns the police are going after his kid, he makes a veiled threat to Megan about her own daughter.

Lacey is MIA for a spell, but Megan eventually tracks her down. Mother and daughter get into heated argument. Lacey's been frustrated by her mom's diligence in caring for her diabetes. Peter advised her to not let the diabetes control her. That's why she didn't answer her cell when her mom called. This leads to another heated argument between Megan and Peter.

Further investigations at the crime scene suggest that Wilson Polley actually did kill Niki. Megan believes someone let him out of jail, then let him back in after the killing. It's a wild theory, but right on the money. Wilson kills the prison guard he was in cahoots with to make a daring prison escape. He later calls Megan to congratulate her for foiling his little plan. The frightening thing is that the call comes from inside the building.

Everyone is at a baby shower for Bud and his wife. Megan is alone in the office when she sees Wilson heading towards her. The killer breaks into her office, knocks her out and ties her to a chair. When Megan awakens, Wilson taunts her with the embalming hook. He covers her mouth with duct tape. Wilson says he's going to make an exception with his latest prey. For Megan, he intends to rip out her brain while she's still alive.

DING! The elevator door opens. Peter steps out. He sees Megan tied up in her office, but Wilson gets the drop on him. A fierce struggle ensues as Megan works to free herself. Peter is in trouble. Wilson is beating on him close to the edge of the balcony. Then...BANG! Megan shoots Wilson in the shoulder. This gives Peter the opening to toss the serial killer over the ledge where he plunges to his death. Megan sees that her partner is hurt, and not just from the beating. The embalmer's hook is jutting out of his gut. He tells Megan that he's okay, but clearly he isn't. We're left with the unsettling image of Megan holding her wounded partner in her arms.
