The series revealed the deaths of 43 children at unregulated day-care homes in Virginia since 2004. About half the deaths were sleep-related and 10 involved physical abuse. In that same time frame, 17 children died in licensed day cares. Child care experts estimate that unregulated providers care for about one-third of all children in day care in Virginia. Unregulated providers are subject to no background checks, no training and no inspections. Because regulators don't even know where the homes are located, the finding of the 43 deaths was news to government officials.
