Isaac Lahey is a student at Beacon Hills High School who is also on the lacrosse team. He works at the graveyard in Beacon Hills. We first meet Isaac, he is working late at night at the graveyard when something knocks over his backhoe dropping him into an empty grave. He then witnesses something digging up a grave. Derek Hale helps him climb out of the grave. During an interview with Sheriff Stilinski, it is hinted that Isaac's father abuses him, as evidenced by a black eye that he claims he got playing lacrosse. Isaac later meets with Derek in an abandoned train warehouse.
