“At this point, I’m not going to give out any names,” Wickersham said. “We’re working with the families, we’re trying to do identification, we’re trying to find out who was operating the vehicle. We always ask the public if there was somebody here at the time of the crash that may have witnessed it — please give the Sheriff’s office a call, because we really want to have a good basis of what really transpired out here.”

Wickersham said that the driver and passengers of the Jaguar were all male and 17 or 18-years-old. It is not known whether alcohol was a factor.

Officials earlier had said the incident involved people on bikes and pedestrians, but that information turned out to be incorrect.
