In 2010, the 30-year-old Richmond native was found not guilty by reason of insanity after the death of her son, Raijon Daniels, in 2006, the Contra Costa Times, of Walnut Creek, Calif., reported.
But in March, doctors determined she does not pose a risk to society and she was released into Contra Costa County's Forensic Conditional Release Program.
The program arranged her housing and will oversee her treatment, the Times reported, and if she wavers, she will face a court-ordered return to the hospital.
The victim's father, Desmond Daniels, said he has difficulty accepting Moses' release.
"How can three years pass and she be OK after the acts that she did? How could someone who put Pine-Sol in a child's food, allow a child to jump from a second-story building, how could they be a model patient?" he said.
The boy was tortured with high-pressure hoses and household chemicals for at least a year before he died, the Times reported.
