The backstory:

The crash happened around 8:45 p.m. on Jan. 20, 2024, at the intersection of Highway 36 and Lake Elmo Boulevard. 

Charges say a Ford vehicle was stalled in the left lane of eastbound Highway 36 due to a mechanical issue and had its emergency lights on. 

A driver of another vehicle moved over to avoid the stalled vehicle, but the driver of a Nissan Pathfinder failed to do the same and struck the Ford from behind.  

Morgan Petersen, a 5-year-old girl in the Ford vehicle, was significantly injured in the crash and later died from her injuries.

"She was always happy. She was a great little girl. She was the light of my life. Every day she woke up, and she wanted to do something nice and listen to music videos and dance," her father previously told FOX 9
