PGA pro Sean Fredrickson died in a plane crash in Idaho over the weekend, a tragic accident that also killed his son and two stepchildren, officials said.

The Kootenai County Sheriff’s Office said Fredrickson and his family died Sunday afternoon when two planes collided, mid-air, over Lake Coeur d’Alene before sinking in more than 125 feet of water, according to FOX12. Officials said eight people were aboard but no one survived.

“My husband's in the golf industry and time off in the summer is extremely rare. So we literally never had summer vacations. This was the first time that we had gone anywhere in the summer," April Fredrickson, Sean’s wife, told People.

She said her husband had always wanted to go on a seaplane but since she already had, she decided to sit out. She said she waited well over an hour without seeing her family return on what should have been a 20-minute flight and that’s when she was approached by two sheriff’s deputies.

“It went through my mind that this might be the last time I see my family,” she recalled thinking before seeing her family depart. “Anytime you send your entire family on something that seems kind of risky, you know, that goes through your mind. And so it did."
