Stella Nickel's Polygraph Test

Stella Nickel was the prime suspect in her husband's murder. The lie detector results were not indisputable as the machine's accuracy had always been debatable. Investigators knew the test results wouldn't hold up in court, and there was still the matter of Susan Snow's murder. With no evidence to arrest her, Stella Nickel was free to go. After a night spent in jail, Stella was released.
