Who was Cordelia Kuether?

Cordelia Kuether, four, was killed on April 12 in a two-car collision as she stopped to pet a dog at the intersection of North 21st Street and Saemann Avenue in Sheboygan.

Kuether's great-aunt asked for drivers to be more aware on the road. "Our families wishes and simply asks that people be more aware and focused while driving," she wrote in a GoFundMe post that has since ended.

"Pay attention to your speeds, pay attention to other cars, pay attention to stop signs and stop at them, pay attention to others on or around the roads, don’t look at your phones while operating your vehicles, don’t drive while intoxicated or under the influence of anything," she said.

"It only takes one missed step in driver awareness for tragedy to result," she added.

Nathan Heitzmann quickly admitted to killing the young girl

The convicted killer quickly took responsibility for the accident that killed the young girl and injured two other children, according to the criminal complaint obtained by ABC affiliate WISN.

"This is my fault," Heitzmann reportedly said, adding "I looked, I stopped at the stop sign OK, looked back and forth, saw them playing on the corner when I looked to the right, I did only look once, I’m not gonna lie, and it was kind of quick, and I did not see any car, but I am assuming they were behind my A-pillar, that was just perfect out of my view, it’s my fault."
