Rodriguez met her husband Frank, a special education teacher, while they were employed at a camp in San Luis Obispo, California.

She was suspected of poisoning Frank's tea with oleander leaves, loosening the gas cap on their clothes dryer, and finally adding antifreeze to her husband's Gatorade.

In her sentencing, Los Angeles County Superior Court Judge William R. Pounders stated that she killed her husband in an "exceptionally cruel and callous" way and that her guilt had been proved to be "an absolute certainty...In the past 20 years, I have never seen a colder heart."

This time the district attorney declined to seek the death penalty and she was subsequently resentenced to life in prison without the possibility of parole.
