The investigation continues into a crash that killed a six-year-old near Plainfield earlier this month.
According to the Waushara County Sheriff, the State Patrol's reconstruction of the crash could take several months. After that, the sheriff says the investigation will move forward.
Officials say a pick-up truck went around a stopped school bus that had its lights flashing and hit six-year-old Mary Ana Kranz. Her four-year-old sister was also struck and is recovering.
A 76-year-old man was driving the pickup truck.
