A Southern California science teacher has been fired for performing in a pornographic video.

Oxnard School District trustees voted in closed session Wednesday night to fire Stacie Halas, who taught seventh- and eighth-graders at Richard B. Haydock Intermediate School.

She had been on paid administrative leave since her appearance on the video surfaced last month. No students are in the video.

The video, available on adult sex websites, was apparently produced before she became an Oxnard teacher in 2009.

Superintendent Jeff Chancer tells the Ventura County Star that her return to class would be disruptive.

Halas has 30 days to appeal the decision by requesting a hearing with an administrative law judge.

Halas could not be reached, and the teacher union declined comment.
