Buffalo Grove High School students return to class after tragic crash and fire.

Students and staff at Buffalo Grove High School are returning to class for the first time since four of their classmates were killed in a fatal crash on Tuesday. The school held a moment of silence to remember the victims, who were identified as Ricky Barcenas, Jesus Rodriguez, Richard De Ita, and Kevin Hernandez. The crash occurred when the driver of the vehicle the teens were in went through a red light. The school had canceled classes for the past two days due to an unrelated fire.
