Speed and alcohol are suspected factors in a late-night car crash in St. Croix Falls, Wis., that killed a 29-year-old driver whose car went airborne and struck several trees.

The crash occurred about 2:45 a.m. Saturday on 200th Street just east of the St. Croix Valley Raceway, according to the Polk County Sheriff’s Office.

Killed was Preston Wilson, of Frederic, Wis., the Sheriff’s Office said. His passenger, Anthony Kralewski, 30, of Centuria, Wis., survived his injuries and was taken to Regions Hospital in St. Paul where he was in fair condition Tuesday morning. Neither was wearing a seat belt, authorities said.

According to the Sheriff’s Office:

Wilson was speeding north on 200th St. and attempted to brake as he approached a corner, but the car went airborne over a driveway and struck a clump of trees in a ditch.

“Alcohol is believed to have been a factor in this crash,” read a statement from the Sheriff’s Office.

The day before the crash, Wilson’s Facebook page included the posting from him, “drinkin with my homies.”
