It's time for defense lawyers to disclose their strategy in the case of a woman accused of killing her 5-year-old son and documenting his decline on social media.

Lacey Spears of Scottsville, Kentucky, is charged with depraved murder and manslaughter in the salt poisoning death last year of Garnett-Paul Spears.

Opening statements began Tuesday in New York.

Prosecutors say Spears fed her son large amounts of salt through a stomach tube, causing brain swelling and death. They believe she administered the salt in his hospital room after he was admitted for seizures.

His mother had written online about Garnett's failing health.

Spears' attorneys haven't publicly outlined the defense. They insisted there will be no mention of Munchausen by proxy, a disorder in which caretakers secretly harm children to win sympathy.
