Welty first married James Goodyear, a sergeant in the
United States Air Force. He died on September 16, 1971, in
Orlando, Florida. His death was initially believed to be
natural causes. Two years later, she moved in with Bobby Joe Morris, a resident of
Trinidad, Colorado. He died by poison in January 1978. Later that year, she legally changed her name to "Buenoano" (corrupted
Spanish for "good year"). Around 1980, Buenoano's son Michael, whom she resented throughout his life because he was born out of wedlock, became severely ill, with symptoms including
paraplegia. On May 13, 1980, Buenoano took Michael out in a
canoe in
Milton, Florida; the canoe rolled, and Michael, with no life jacket and weighed down by his arm and
leg braces, drowned. Following his death, Buenoano opened a beauty salon using the proceeds from his life insurance. While he was recovering from his injuries, police found several discrepancies in Buenoano's background. Further investigation revealed that in November 1982, she began telling her friends that Gentry suffered from a
terminal illness. Authorities found that the "vitamin pills" Buenoano was giving Gentry contained
arsenic and
paraformaldehyde.
Exhumations of Michael Goodyear, James Goodyear, and Bobby Joe Morris showed that all were given arsenic. James Goodyear and Bobby Joe Morris were found to have died of arsenic poisoning. Buenoano received substantial
life insurance payouts after each death. She was arrested in 1983 on multiple counts. ==Conviction, imprisonment, and execution==
