(KCEN) -- Police have made a third arrest in connection with the death of a five-year-old San Antonio boy. Josiah Williams was found unresponsive with suspicious injuries at a Southeast San Antonio home on December 27th.
Williams' father and stepmother were arrested the next day.
Then Thursday night, police arrested Crystal Williams' mother, 48-year-old Gloria Proo.
Proo was often the boy's main caregiver and assumed a lead role in his discipline.
Police say Proo allowed the child to live in conditions that lacked proper nourishment and participated in a pattern of physical assaults.
