“We’re unable at this time to determine if alcohol or any other impairments to their driving were factors in the crash,” said Shaw. “So, right now we are waiting for autopsy results and also for our crash investigation unit to do their final paperwork before we can determine the actual cause.”

The freeway was closed for about three hours, but has since reopened.

An investigation is ongoing.
