A report from the Department of Child Safety details a history of alleged abuse that almost killed a 16-month-old Tucson boy.
The report said Anissa Winders, the boy's mother, was investigated in April 2017 but there was no evidence of neglect.
In October, Winders' son was taken to the hospital in critical condition while in Cody Thomas' care at a home in the 5600 block of East 24th Street,
Sgt. Kim Bay, spokeswoman for the Tucson Police Department, said at the time 22-year-old Thomas was arrested on a felony child abuse charge.
A grand jury charged Winders last month for the same incident.
The child has been placed in a relative's home.
DCS had no prior reports on Thomas, who Bay said is not related to the child, before the October incident.
