A Springfield police spokesman says officers responded to a city home last Saturday for reports of a child not breathing. Sgt. John Delaney says the little girl’s scalp was covered in mayonnaise and a plastic shopping bag was placed over her head, a common home remedy for head lice. The girl was left unattended and apparently fell asleep, allowing the bag to slip down over her face, suffocating her. The matter remains under investigation and no charges have been filed. The state Department of Children and Families is also investigating.
