A woman who blogged for years about her son's constant health woes has been convicted in New York of poisoning him to death with salt.

A jury on Monday found Lacey Spears, of Scottsville, Kentucky, guilty of second-degree murder in the death of 5-year-old Garnett-Paul Spears.

Prosecutors contended that Spears reveled in the attention Garnett's illness brought her and that she force-fed him heavy concentrations of sodium through a stomach tube.

Several doctors testified that there was no medical explanation for the spike in Garnett's sodium levels that led to his death.

Prosecutors say the 27-year-old Spears eventually killed the boy because she feared he would start telling people she was making him ill.

The defense portrayed Spears as a caring mother and Garnett as sickly.
