New Details Emerge in University of Idaho Killings: What We Know

“There’s no words that I can really describe her — how amazing she was and how wonderful of a person she was,” Mr. Schriger said.

Kaylee Goncalves, who was from Rathdrum, Idaho, had been set to graduate early in December and planned to move to Austin, Texas, with one of her close friends in June. The friend, Jordyn Quesnell, said Ms. Goncalves had secured a position with a marketing firm and was excited to explore more of the country.

“We wanted that adventure,” Ms. Quesnell said. “I would be like, ‘Let’s go do this,’ and she’d be like, ‘Down!’”

Alivea Goncalves said her younger sister and Ms. Mogen had served as bridesmaids for her wedding. Her sister, she said, still shared a dog with her recent boyfriend, and the two had seemed likely to get back together.

Ethan Chapin, from Conway, Wash., was one of three triplets and had spent much of Nov. 12, the day before the killings, with both of his siblings, who are also University of Idaho students, said their mother, Stacy Chapin. In the evening, they had all attended a dance together held by his sister’s sorority, she said.

“My kids are very thankful that it was time well spent with him,” Ms. Chapin said. “He was literally the life of the party. He made everybody laugh. He was just the kindest person.”

Mr. Chapin played basketball in high school and was known by friends and family members for always having a big smile, ever since he was a baby. Ms. Chapin described her son as “just the brightest light.”
