Skye McCole Bartusiak, the actress who played Mel Gibson's youngest child in "The Patriot," died Saturday. She was 21.
The woman's boyfriend found her dead in her bed at her Texas home.
"We think she had a seizure and choked and nobody was there," Helen McCole Bartusiak, the actress' mother, told CNN.
"We lost our girl. She was a kind and really beautiful girl," she added.
Actress Abigail Breslin, a friend of Bertusiak's, expressed her grief at the passing on Twitter.
