Suspected murders: Husband, son, boyfriend
Status: Executed March 30, 1998
Judi Buenoano was the first woman to sit in Florida's electric chair when she was executed in 1998 for the murder of her husband, James Goodyear. Buenoano was not suspected of involvement in his death until she attempted to kill her boyfriend 12 years later by giving him arsenic-laced "vitamins" and then blowing up his car. When her husband's body was exhumed, it was found to contain arsenic.
That same year, she was convicted of killing her partially paralyzed 19-year-old son by intentionally capsizing a canoe while he was in it.
Over the years, she collected more than $240,000 in insurance money for the deaths of her husband, son and a previous boyfriend in Colorado. Buenoano never admitted any of the killings.
