The state’s Department of Children and Family Services tried to reach Andrea Luncsford earlier this month after being told there was a substantial risk to a child. Deborah Lopez, a DCFS spokeswoman, said her agency had been talking to Luncsford as early as Sept.

Andrea N. Luncsford, 25, was charged Wednesday for her alleged role in the death of her 1-month-old son, Grayson, who was found dead Monday in the 2400 block of North Peoria Avenue after he was left inside a U-Haul truck for hours.

Residents on North Peoria Avenue said a U-Haul pickup truck that had a dead baby inside had been parked in a driveway for several hours and the windows had been rolled up.
