Kane County Sheriff Ron Hain said based on accident reconstruction and the vehicle's black box data, Schmidt was estimated to have been traveling 5-8 miles over the 45-mile-an-hour speed limit on Empire Road in Campton Township when the crash occurred.

Emil, 19, and Grace, 20, Diewald were passengers in the 2013 Lexus SUV Schmidt was driving.

A 17-year-old South Elgin girl, who was also in the vehicle, was flown to Lurie Children's Hospital in Chicago, but no condition reports about her are available.

Kane County officials said no one on the school bus, which was taking students home from Lily Lake Grade School, was injured.

Many at a vigil in November spoke of the siblings' positive energy and loving hearts.

Schmidt is being held in the Kane County jail on $100,000 bond, with $10,000 or 10% required to be released on bail, records show.

He is scheduled to appear in court Jan. 6.
