A 68-year-old Coon Rapids woman died Friday after a single-vehicle accident in Isanti County, authorities said.

She was identified on Saturday by her family as Doris Tadych, a retired hair stylist who had been riding in a minivan driven by her husband, Denis Tadych. He was released from North Memorial Medical Center in Robbinsdale on Saturday after being treated for a concussion.

Denis Tadych, 67, was driving south on Hwy. 47 when his minivan went onto the right shoulder and off the road before hitting a tree, according to the State Patrol.

The road was dry at the time.

Denis Tadych said Saturday that because of his head injury, he does not recall exactly what happened. "That's the big question," he said. "I'm trying to find answers because it's really bothering me."

What he remembers, he said, was driving south behind an SUV that was pulling a boat on a trailer on the undivided highway. The couple were talking.

"There was a lot of ­traffic coming the other way," he said. "I don't know if I swerved for something other than the trailer. I don't think so."

He came to, he said, as people were trying to help him get out of his minivan. He went with them to the other side of the van to tend to his wife, who was badly injured. She had been wearing a seat belt, and an air bag deployed, the patrol said.

Tadych said the paramedics told him his wife had a strong pulse when she was loaded into a helicopter and flown to North Memorial Medical Center.

He said troopers are going to check his vehicle, a 2012 Kia Sedona. The right front wheel was not on the van when he looked at it after the accident, he said.

No matter what the cause was, Denis Tadych said sadly, "it's not going to bring my wife back."

The two, who had three grown children, would have celebrated their 49th wedding anniversary on Labor Day.

In the 1970s, Doris Tadych ran her own beauty shop, Doris' Cards and Curls, where she also sold greeting cards. After closing her shop on Penn Avenue at 35th Avenue N. in Minneapolis, she leased a styling station at Crowning Glory Beauty Salon in Robbinsdale before retiring at age 62, he said.
