17. Conscience

A neurologist is found dead in a swimming pool, murdered by a combination of chemicals in her swimming gloves. Goren and Eames look at her research into whether persons in a vegetative state can communicate and are led to the situation of Laraine Farrell ( Dee Pelletier ), a woman with a heart condition who had heart failure while hiking with her husband Mark ( John Savage ) and son. Their investigations show that she stole thousands of dollars from the company where she worked and hid it in a fund, but her husband knew this and so he caused her to collapse so he could access the funds. The Major Case Squad stage an experiment at Laraine’s bedside to test if she can communicate, preying on Mark's guilt to elicit a confession from him.
