A PGA golf pro, his son and two stepchildren were among the eight people who died in an Idaho plane crash Sunday, multiple news outlets are reporting. According to KPTV, Oregon residents Sean Fredrickson, 48; son Hayden Fredrickson, 16; and stepchildren Sofia Olsen, 15, and Quinn Olsen, 11, were killed Sunday afternoon when two planes collided over Idaho's Lake Coeur d'Alene and crashed into the water. All eight people on the two planes died in the crash, the Kootenai County Sheriff's Office said. Authorities said Fredrickson and the children were on board a Brooks Seaplane piloted by 58-year-old Neil Lunt of Liberty Lake, Washington, at the time of the crash, the Spokesman-Review reported. Officials have not yet identified a sixth person who also was on the plane. The two people on board the other plane, a Cessna TU206G, have been identified, but officials have not publicly released their names, according to the Spokesman-Review. As of Tuesday, crews were still working to recover two of the victims' bodies, the newspaper reported. Fredrickson, the Pacific Northwest PGA Section's president, was the lead golf pro at Oregon's Oswego Lake Country Club, according to KPTV. “A rising star in the PGA, Sean led the Section through an unprecedented time, first taking the reins a year early as president and then leading us wisely through this pandemic,” the Pacific Northwest PGA Section said in a statement. “We are all better because of Sean’s leadership over the past 12 years.” Fredrickson's wife, April Fredrickson, told KPTV that her family 'died while they were on an adventure.' 'I think that, at the end of the day, they died doing what they loved, which was ... being together,' she told the news outlet. Read more here or here.
