Prosecutors are seeking the maximum sentence for a woman convicted of killing her 5-year-old son by poisoning him with salt.

Lacey Spears of Scottsville, Kentucky, was found guilty last month of second-degree murder in the death of Garnett-Paul Spears at a suburban New York hospital.

The 27-year-old Spears was found guilty of force-feeding heavy concentrations of sodium through the boy's stomach tube.

At Wednesday's sentencing, the maximum that can be imposed is 25 years to life. The minimum is 15 to life.

Defense attorneys said the evidence did not prove murder. They have promised an appeal of the conviction.

Spears did not testify at the trial.
