It appeared the SUV was heading south when the driver lost control, officials said.The SUV came to rest in a heavily wooded area. The couple from Omaha were ejected from the car and pronounced dead at the scene.Authorities said it appeared neither was wearing a seat belt. It's unknown whether alcohol was a factor in the crash, according to a release from the sheriff's office.The accident is under investigation by the Cuming County Sheriff's Office.Frank and Yvonne Pivonka were high school sweethearts. When they didn’t show up Sunday afternoon, family members said they knew something was wrong. They were found a day later.“They always said, ‘What’s another kid?’ They loved their children more than anything. Yvonne and Frank’s family was the world to them,” said Cathy Cattlett, Yvonne Pivonka’s sister.Their children range in age from 3 to 20.“The 3-year-old asking, ‘There’s my daddy’s truck. Can I go see him?’ is probably the hardest thing. I don’t know how to explain to her that she won’t, she can’t see them,” Cattlett said.Family members said the couple left for West Point on Saturday, and typically would spend the night on such a trip. But when no one could get ahold of the couple, the family went out to find them.“(We were) driving around trying to find them because it wasn’t like them not to answer their phones. We were calling them nonstop,” said Brenda Pivonka, Frank Pivonka’s sister.The oldest child, Angel, came home to console her younger sisters. Their two aunts are taking on a role they promised they always would.“Step up to take care of the kids, yeah, they would have wanted the two of us to make sure they become everything they want to become. Brenda and I will do the best we can to make sure they make their parents’ memories proud,” Brenda Pivonka said.Relatives said they heard reports that the couple tried to avoid a deer that was found dead on the side of the road, but authorities have not confirmed that.A GoFundMe.com page has been set up, as well as a fund at Centris Federal Credit Union to raise money for the family. There is also a benefit concert scheduled for this weekend.
