Mollie Fitzgerald, an actress who had a minor role in Captain America: The First Avenger, was arrested in Olathe, Kansas, on Tuesday for fatally stabbing her mother.

The 38-year-old actress was charged with second-degree murder after officials discovered her 68-year-old mother, Patricia Fitzgerald, dead in her Olathe, Kansas, home on December 20.

According to the Olathe Police media release, “Fitzgerald was contacted on the scene and transported to a local hospital with minor injuries.”

Fitzgerald played the character of “Stark Girl” in the 2011 Captain America film. Additionally, she was also an assistant to the film’s director Joe Johnston.

“Being a part of this production has been one of the best experiences of my life,” Fitzgerald told a comic book publication in 2011.

Besides being an actress, Fitzgerald is a producer and director for films such as The Creeps and The Lawful Truth.

According to Patricia Fitzgerald’s brother, Gary Hunziker, his sister was in the process of moving back to the Kansas City area after living several decades in the Houston area. Hunziker told the newspaper that the sister’s death was shocking for the family.

“We were shocked,” he said. “It doesn’t matter the circumstances, the loss of a sister is what it’s all about.”

Fitzgerald’s next court appearance is scheduled for January 9.
