SACRAMENTO, Calif. – A California high school teacher was arraigned on Monday at a Sacramento court accused of having sex with a student in a car as her two-year child was strapped into the back seat.

Margaret De Barraicua, 30, a teacher trainee, was charged with four counts of unlawful sexual intercourse with a minor, a 16-year-old student. The married woman was caught having sex in the late afternoon last week in what was apparently a consensual agreement, officials said.

“We received a call about a suspicious parked vehicle at a school here in Sacramento,” said local police spokesman Justin Risley. “They got there and observed two people, windows-steamed-up type of thing.”

“They found them to be partially clothed and engaging in what appeared to be sexual intercourse.”

Her two-year old son was strapped by a seat belt in the back of the car during the time, he said.
