How old was Jayne Mansfield when she died?

Jayne Mansfield (born Vera Jane Palmer; April 19, 1933 – June 29, 1967) was an American film, theater, and television actress. She was also a nightclub entertainer, a singer, and one of the early Playboy Playmates. She was a major Hollywood sex symbol during the 1950s and early 1960s, while under contract at 20th Century Fox.

Although Mansfield's film career was short-lived, she had several box-office successes and won a Theatre World Award and a Golden Globe. She enjoyed success in the role of fictional actress Rita Marlowe, both in the 1955–1956 Broadway version and the 1957 Hollywood film version of "Will Success Spoil Rock Hunter?" Her other major movie performances were in "The Girl Can't Help It" (1956), "The Wayward Bus" (1957), and "Too Hot to Handle" (1960).

In 1967, Mansfield was in Biloxi, Mississippi, for an engagement at the Gus Stevens Supper Club. After two appearances on the evening of June 28, Mansfield, Sam Brody (her attorney and companion), their driver Ronnie Harrison (age 20), and three of her children (Miklós, Zoltán and Mariska) left Biloxi after midnight. At about 2:25 a.m., on U.S. Highway 90 west of the Rigolets Bridge, the Buick crashed at high speed into the rear of a tractor-trailer that had slowed behind a truck spraying mosquito fogger shrouded in an insecticide fog. The three adults in the front seat died instantly. The children, asleep in the rear seat, survived with minor injuries. Mansfield died at the age of 34.
