PGA Pro and Lake Oswego, Oregon resident Sean Fredrickson, his son Hayden Fredrickson and stepchildren Sofia and Quinn Olsen were confirmed by family members as four of the victims in Sunday's crash after two planes collided and fell into Lake Coeur d'Alene, Idaho.

The crash site is between Powderhorn Bay and Black Bay on Lake Coeur d'Alene, the midair collision happened about 2:20 Sunday afternoon.

April Fredrickson, Sean's wife and Sofia and Quinn's mother, said that her family had "died while they were on an adventure," and expressed her heartbreak over the tragedy.

"Everyone was so excited to be on that plane…I think that, at the end of the day, they died doing what they loved which was, you know, being together...I don’t know a person that did not like my husband. He just had an infectious personality. Always wanted to take care of everybody else."

The Kootenai County Sheriff’s Office confirmed in a press release that two planes, a Cessna TU206G and a de Havilland DHC-2, crashed into each other above the lake.

The FAA and the National Transportation Safety Board are currently investigating the crash.

The Professional Golfers' Association of America (PGA), where Sean worked as the president of the Pacific Northwest Section, issued a statement on their website and remembered him for his love of mentoring others.

"Sean was an incredible father, husband, PGA Professional, mentor, and leader," the organization wrote. "There are never words to communicate the pain of such a loss."

"We are all better because of Sean’s leadership over the past twelve years," the statement continued. "His passion to help many of you was driven by his genuine desire to serve his fellow PGA Professionals. You will carry on this passion. As you remember Sean, reflect on the enthusiasm, the integrity, the passion, and the love we saw in him every day. We will miss you, our friend."
