Sebastian Andrew Hintt was 5 years old when he was killed on December 19, 2021, in Belvidere, Illinois. His father Andrew Hintt and 7-year-old brother Benjamin Hintt also died of gunshot wounds; the Boone County Coroner’s Office classified all three deaths as homicides. The three bodies were found in the family home on Union Avenue after the landlord called 911 because the boys’ mother could not reach Andrew.

Investigators recovered 9mm shell casings at the scene, but the firearm used was not recovered. Police said a 24-year-old man from Huntley, Illinois, Alize Smith, was seen leaving the Hintt residence the day of the killings and was later located driving Andrew Hintt’s stolen Jeep Grand Cherokee Trackhawk. Smith was arrested on December 21, 2021, after being turned in by a friend in Michigan and was charged with three counts of first-degree murder; he was being held without bond.

The community expressed grief and support for the surviving family members. Does anyone have information about the family, the vehicle, or the days leading up to December 19, 2021?
