BOONVILLE, Mo. (KMIZ)

The Missouri State Highway Patrol said 20 vehicles were involved in a crash that shut down Interstate 70 westbound on Monday.

The MSHP crash report shows a van was involved in an unrelated crash before the pile-up at 12:55 p.m. Troopers said the initial crash blocked both lanes of I-70 West, the other 19 vehicles weren't able to slow down within enough time. Three semi-trucks were also involved in the crash.

Two people hurt in the crash were taken to the hospital. Troopers said a 69-year-old Patricia Henning, of Overland Park, Kansas, had moderate injuries and 19-year-old Andrew Boyer, of Eureka, had serious injuries.

MSHP closed traffic on the interstate for more than two hours between 1:30 p.m. and 3:45 p.m. Traffic was backed up between the Rocheport bridge and the Stadium Boulevard exit on I-70.

Troopers didn't say if the weather played a part in the crash. The crash report shows 15 vehicles were totaled.
