I would think his blunt head injury was from the van being crushed (Did they not find some cars under the bridge edge that was in the water?)

Nearly a dozen cars plunged into the river. Among the dead motorists were Clements, who was to have been promoted to major next week, and the family's German shepherd "Ostar." The family's new silver Honda Odyssey van was crushed and rendered nearly unrecognizable by the crash. The dog's travel carrier was perched atop remnants of the van, giving Clements' wife, Nicole, the first clue that her husband had been involved, family members told a hometown newspaper.
