Zach Twedt, a hawkeyefootball linebacker, was leaving a Walmart in Iowa City when he spotted two stranded girls. Riley Uthe’s car had just run out of gas on her way to the gym with her best friend Emma Kuepker. It was a familiar sight for Twedt, who stopped to help single mom Tina Gunn, who had a flat tire near Story City, so she could get home to Omaha last year in July. Gunn detailed Twedt's good deed on social media and the story went viral. A night before the anniversary of meeting Gunn, he did it again. Twedt pulled over in his truck to help the pair of 17-year-old girls, who were traumatized from an event they experienced the night before.
