According to KCCI-TV, Yates told Bahena Rivera at his sentencing, "Mr. Bahena Rivera, you and you alone forever changed the lives of those who love Mollie Tibbetts."
The Des Moines Register reports Tibbetts’ mother Laura Calderwood wrote a victim impact statement, which was read by an Iowa attorney general office staffer. In it, Calderwood said, "Mr. Rivera, I come here today not because I feel the need to address you. However, I come here to give a voice to our daughter, granddaughter, sister, girlfriend, niece, cousin and friend, Mollie Cecilia Tibbetts. Mollie was a young woman who simply wanted to go for a quiet run on the evening of July 18th, and you chose to violently and sadistically end that life."
Calderwood wrote, "Because of your act, Dalton Jack will never get to give Mollie the engagement ring he had purchased for her. Because of your act, Mollie’s father, Rob, will never get to walk his only daughter down the aisle. Because of your act, Mr. Rivera, I will never get to see my daughter become a mother."
