MOSCOW, Idaho – Thousands of people gathered at the University of Idaho in Moscow on Wednesday night to pay tribute to the four students who were killed on Nov. 13.

Ethan Chapin, 20; Xana Kernodle, 20; Madison Mogen, 21; and Kaylee Goncalves, 21, all University of Idaho students, were stabbed to death likely while sleeping on Nov. 13 between 3 and 4 a.m. in a Moscow, Idaho, home on King Road near the college campus, according to police.

The attacker used a "fixed-blade knife" to kill the victims, police said, adding that a suspect hasn't been identified as of Wednesday.

Several families of the victims spoke at the vigil, which concluded with a moment of silence for each person killed in the attack.

Steve Goncalves, the father of Kaylee, spoke at the vigil and said that "we lost four beautiful souls."

He said that Kaylee and Mogen have been best friends since sixth grade and did everything together.

"They did homework together. They came to our house together. They shared everything… They convinced us. They made a proposal to go to high school, to a regular high school. So then they went to high school together," Goncalves said.

Their friendship continued into college, where Goncalves said that the two got an apartment together "and in the end that they died together in the same room, in the same bed."

"It's a shame and it hurts. But the beauty of the two always being together is something that will well, it comforts us. It lets us know that they were with their best friends in the whole world. It's like a book," Goncalves said.

Chapin told the audience to "spend as much time as possible" with family, adding that "time is precious and it's something you can't get back."
