Township High School District 214 confirmed Wednesday morning that the four teenagers were Buffalo Grove High School students. A fifth student was hospitalized.

“Our thoughts and prayers are with the families and friends of these students during this time of tragedy. We also offer condolences to all Buffalo Grove students, families and staff members,” the school district said.

Speed and a disregarded traffic signal appear to be the primary factors involved in the crash, police said.

One of the vehicles involved struck an electrical pole and caused a power outage in the area.

The Northwest Suburban Major Case Assistance Team’s Serious Traffic Accident Reconstruction unit along with Wheeling police crash investigators were on the scene recovering evidence and investigating.

Wheeling social service workers have also been involved and are working with the families “as they begin to process this terrible event,” police said.

The school district said they have made counselors available to help the school community “deal with this tragic loss.”

Students returned to in-person class at Buffalo Grove High School on Friday.

Wheeling Police Chief James Dunne said he extends his heartfelt condolences to the families of the deceased.
