Former "teacher of the year" arrested for allegedly having sex with 16-year-old: "There may be additional victims"

A former high school "teacher of the year" has been arrested in California for allegedly having sex with a 16-year-old boy and authorities said they "believe there may be additional victims."

Tracy Vanderhulst, a 38-year-old math teacher at Yucaipa High School, was arrested late Thursday night for unlawful sexual intercourse involving a minor and held on $30,000 bail, the San Bernardino County Sheriff's Office said in a news release. It was not immediately clear if the minor was a student at the high school.

In a tweet that has since been deleted, the school said that Vanderhulst "offers up a rigorous mathematics curriculum and deep caring for her students," CBS Los Angeles reported.
