San Antonio police have a made a third arrest in connection with the death of a 5-year-old boy.
Gloria Proo, 48, was arrested late Thursday night on charges of injury to a child.
Investigators said Josiah Williams was found dead with bruises and cuts all over his body at a home in the 3900 block of Gale Avenue.
The boy's father and stepmother, Charleston and Crystal Willliams, were arrested last week.
Investigators said the couple failed to seek medical attention for the boy.
According to Proo's arrest warrant, the 5-year-old was left in her care for hours during the time period in which he was allegedly abused.
Police said Proo played a lead role in the discipline of the child, which eventually led to the boy's death.
Gloria Proo is the mother of Josiah Williams' stepmother.
Proo was booked into the Bexar County Jail on $75,000 bond.
