The mother of Ethan Chapin, one of the four University of Idaho students killed on Nov. 13, says her son "loved unconditionally" and "touched lives we had no idea existed."

Ethan Chapin, 20, Xana Kernodle, 20, Madison Mogen, 21, and Kaylee Goncalves, 21, were stabbed to death by 28-year-old suspect Bryan Kohberger during the early morning hours of Nov. 13 in Moscow, Idaho.

Stacy Wells Chapin wrote in a Facebook post Wednesday that she had just dropped off her other two children, Maizie Chapin and Hunter Chapin, at the University of Idaho on Wednesday. Maizie and Hunter attend the same school as their late brother Ethan. 

"Yesterday, we successfully dropped them off back at the University of Idaho. Hunter was very glad to be back at the fraternity and Maizie was warming up to the idea but it was so good to hear all of the girls squeal with delight upon seeing her. It did this momma’s heart good to hear it!!," Stacy Wells Chapin said.

"He was loyal to all, he was inclusive, carefree, happy, just the best person you could ever meet. The stories are endless and amazing."

Stacy Wells Chapin added that her family has spent "no time being angry," adding "that would be energy not well spent and it still wouldn’t change the outcome."

"We have to look ahead," the mother said.
