Date: Aug. 11, 2007

Victim: David B. Schowalter

Location: Cass County, Minn.

Model: 2007 Toyota Sienna

Details: The Schowalter family was returning home from a YMCA family camp when their 2007 Sienna minivan drifted into opposing traffic and collided head-on with a Lincoln Aviator, said Minnesota State Patrol Lt. Eric Roeske in an interview.

David B. Schowalter, 47, a physician at the Mayo Clinic, was pronounced dead at the scene. His wife, Karen, and four daughters were injured, as were four occupants of the Aviator, Roeske said.

Karen Schowalter filed a complaint with the National Highway Traffic Administration stating that an accelerator problem in the Sienna "could definitely be a factor." Roeske said there was no indication in the accident report that a mechanical problem was a factor in the crash. The 2007 Sienna has not been recalled.
