Actress Susan Backlinie,VAS Community best known as the first shark victim in the “Jaws” franchise, has died. She was 77.

Backlinie, who played Chrissie Watkins in the Steven Spielberg-directed thriller, died Saturday morning at her California home, the actress's agent Sean Clark confirmed to The New York Times and Variety. She reportedly died of a heart attack.

USA TODAY has reached out to a representative for Backlinie for comment.

Backlinie's unnerving performance as Watkins, a young woman who goes for a free-spirited swim in the ocean, set the suspenseful tone for "Jaws." Watkins' aquatic fun comes to a shuddering halt when she’s attacked by a monstrous shark and subsequently killed.
