VANCOUVER, Wash. -- After a wrong-way crash killed a 6-year-old boy and critically injured his cousin and aunt on I-5 north of Vancouver, KATU requested public records and data from the Washington State Patrol.
An analysis of the crash records revealed 22 other crashes also attributed to wrong-way drivers on the stretch of interstate from the Columbia River to exit 14 since the year 2000.
Those crashes killed four people and badly injured 19 others, including the two fatalities and injuries from February's crash.
Troopers determined 10 of those wrong-way drivers were also under the influence of alcohol, two were not paying attention, and one was apparently asleep.
Investigators did not determine causes for the remaining 10 instances.
An official cause has also not been determined for Gage Musgrave's case.
He died after the crash, but troopers said they believed he simply got confused and disoriented near exit 11.
