A mother is pleading not guilty to killing her son with salt.
Lacey Spears faces murder charges for the death of her 5-year-old son Garnett.
Police in New York say they believe she poisoned him with high doses of salt, while they lived at a retirement community where she worked.
Doctors found high levels of sodium in Garnett before but nothing was done.
Police say they believe Spears abused her son for years.
They say she may have killed him to gain sympathy and attention from others.
