A central Illinois couple faces first-degree murder charges in the death of their 5-month-old baby, who was found unresponsive in a car seat that had been placed in a crib.

During the eight days the baby was strapped in the seat, both Hermann and Sargent were home, "playing video games, watching TV, feeding and caring for themselves," Lyons said.

Lawyers in the state's attorney's juvenile division have begun proceedings to permanently remove Hermann's 3-year-old daughter from the home. That child was staying with another family member but is now in the care of Department of Family and Children's Services.
