Five-year-old Garnett Spears died at the end of January after being taken off life support — and authorities are reportedly investigating his mother because the boy was found with high levels of salt in his body.

Twenty-six-year-old Lacey Spears fed her son through a feeding tube connected to his abdomen and a huge red flag for investigators is the high concentration of sodium found in a bag she used to feed Garnett. Spears denies any wrongdoing. (Via The Journal News)

The Journal News dug extensively into the story and reports while Garnett lay in the hospital dying, Spears called a neighbor, who requested anonymity, to go inside her home and dispose of one of the feeding bags. The neighbor retrieved the bag, but called the police.

Lab results revealed a dangerously high amount of sodium content inside the bag.

Authorities are now trying to determin whether Spears suffers from Munchausen syndrome by proxy, a syndrrome that causes parents to harm their children in search of attention or sympathy for themselves. (Via WebMD)

And she started a blog, Garnett's Journey, writing, "Healing takes courage, and we all have courage, even if we have to dig a little to find it."

Spears, who is staying with family in Kentucky, has hired a defense attorney, who says Spears is devastated by the loss of her son.

Rebecca Spears, Lacey Spears' sister, said, "Lacey did nothing to harm him. She loved him and did everything she could to care for him and protect him." (Via People)

As of Monday no charges had been filed against Spears.
