Both drivers survived the crash and are in the hospital, authorities said.

Lasson stressed Thursday that it was still early but that the incident will be investigated fully.

\"We need to be alive to the fact that there could be wrongdoing and if so, there could be a criminal element to this investigation,\" Lasson said, calling it a \"complex, large investigation.\"
