Authorities say a two-vehicle accident in Watertown left one person dead and two others seriously hurt.

The accident happened around 5:25 p.m. Thursday on Highway 20 north of Lake Kampeska on the northwestern edge of the city.

According to the Department of Public Safety, a 2002 Toyota Highlander was driving west when it collided head on with an eastbound 2001 GMC Yukon. Troopers say it appears the Highlander crossed the center line into the eastbound lane.

Watertown police say the jaws of life were required to extract both the driver and the passenger from the Yukon. The 56-year-old man driving the Yukon died from his injuries. A 54-year-old woman who was a passenger in the Yukon was transferred to a Sioux Falls hospital with life-threatening injuries.

The 17-year-old male driver of the Highlander was also hospitalized with life-threatening injuries. No one else was involved in the crash.

Troopers say the female passenger of the Yukon was wearing a seat belt. Authorities are still trying to determine if the drivers of either vehicle were wearing seat belts.
