The child’s mother, Azuradee France, 31, was also charged by Wayne County Prosecutor Kym Worthy with first-degree child abuse, torture and concealing a death, which are all felonies, officials said.
France was arraigned Sunday and pleaded not guilty, the prosecutor’s office told CNN.
Investigators said they are unsure at this point how long the child’s body was in the freezer or when or how he may have died. The medical examiner’s office ruled the boy’s death a homicide, police said.
“The alleged facts in this case have astounded even the seriously jaded,” Worthy said in a statement.
Five other children who lived in the house were checked at a hospital and were being placed into custody of Child Protective Services, police said.
France remains in custody, and her next hearing is scheduled for July 8, the prosecutor’s office said.
