Tammy and Dr. Jeffrey Harris had been married for 11 years when Tammy was diagnosed with lupus. Doctors begin a treatment regimen but her health did not improve. Harris was wheelchair-bound, her weight dropped to just 70 pounds, and her hair and fingernails fell out. 

The couple traveled from Moscow, Idaho to New York in search of a holistic doctor, when Tammy suddenly collapsed in the lobby of the Lotte New York Palace hotel. She died six days later. An autopsy determined that Tammy Harris died from an overdose of the dietary supplement, Selenium. 

 Selenium, a trace mineral is considered safe in small doses, but the city medical examiner found eight times the average amount of Selenium in Harris's system. An investigation revealed that Dr. Harris did not believe his wife had Lupus.

He insisted that she suffered from mercury poisoning from working at a dental office several years prior.  Dr. Harris kept up the pretense that his wife was taking what she had been prescribed by her doctors, but instead, she was taking Selenium, prescribed by her husband.
