A woman whose 4-month-old daughter died after being left in a hot car was sentenced to five years in prison Monday.

Melisa Wildman, 30, pleaded guilty to aggravated manslaughter of a child. She also was sentenced to 15 years probation.

Wildman told police she had consumed Xanax, four or five beers, cocaine and marijuana in a 12-hour period before Savanna died in April 2004.

A sheriff's officer and paramedics had found Wildman unconscious in her car just hours before the baby's death.

Two passers-by roused Wildman and an officer let her drive away, though she had two outstanding warrants against her for failure to appear on two charges of driving with a suspended license.

She later returned to her apartment and passed out again in the car with her baby in the back, police said.

If convicted at trial, Wildman could have faced up to 30 years in prison. Her attorney, Gary Ostrow, did not immediately return a call seeking comment Monday night.
