A woman accused of leaving her infant son in a U-Haul for long enough that he eventually died will be detained before a pending trial on charges of murder and endangering the life or health of a child.

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.

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.
