A chain-reaction crash started by a semitrailer truck on Interstate 94 in Woodbury Thursday killed a motorist in a car, authorities said.

The four-vehicle wreck occurred shortly before 7 a.m. on westbound I-94 near Radio Drive in Woodbury, according to the State Patrol.

As traffic began to slow, the semi rear-ended a car, which then sent one SUV into the back of another SUV, the patrol said.

The car’s driver was identified by the patrol as 33-year-old Andrew S. Russ, of Woodbury.

The other three drivers were the truck driver, Shane T. Michaels, 28, of Marinette, Wis.; and women from Woodbury, Colene B. Erickson, 51, and Bonnie B. Rizzardi, 39. Michaels and Erickson were not hurt, the patrol said. Rizzardi was taken to Regions Hospital with noncritical injuries.
