CHICAGO (AP) _ A woman has been charged with involuntary manslaughter after her infant son died of malnourishment while she was having her nails done at a salon.

Dianna Meeks, 25, was charged Sunday in the death of Dontory Jordan, who weighed just 3 pounds when he died Thursday night. The baby had weighed 5 pounds when he was born prematurely less than two months ago.

The cause of death was listed as failure to thrive and maternal neglect.

Meeks, two relatives and the baby were at Sunny Nails on Thursday when the baby's aunt noticed that the infant, who was wrapped in a blanket, was not moving. Paramedics were called, and the baby was taken to a hospital. Authorities said the baby had died in his aunt's arms at the salon.

Sunny Nails manager Phap Nguyen said the baby's aunt was holding the infant while his mother was having her nails done.

``When she asked her sister for money to pay the bill, she saw something wrong with the baby,'' Nguyen said.

The aunt later said that the boy appeared sick and that they had planned to take him to the hospital the next morning, according to Nguyen.

If convicted, Meeks could be sentenced to two to five years in prison.

Meeks' four other children were taken into protective custody Friday, according to Martha Allen, a spokeswoman for the state Department of Children and Family Services. She said the three boys, ages 6, 4 and 2 years, and a 17-month-old girl were well-fed and appeared to be in good condition.

The department had investigated Meeks last year, but Allen said the case had been closed since October 1996, when Allen and her children moved in with her mother and caseworkers concluded the children were being well cared for. The agency did not know about Dontory's birth until after the baby died, Allen said.
