Sometimes They Come Back (1991)

"With "The Shining" and "Misery" Stephen King scared you to death. Now, he's going to scare you back to life."

Desperate for a job to help him support his family, Jim Norman takes a position teaching high school in the town where his brother was murdered in front of him by teenage bullies twenty-seven years before. The teens who committed the crime are long dead, but now the kids in Jim's new class keep dying and being replaced by new students who look like the deceased hoodlums.
