Authorities responded to Santana's home on July 16 for reports of an unresponsive baby in a bathtub. By the time they arrived, the parents had already taken the baby, identified as Antonio Armando Delgado Jr., to the hospital, where he was pronounced dead four days later.
This isn't Santana's first run-in with the law. Her history was brought up in court on Friday, and includes violation of probation and threatening.
The exact cause of death remains under investigation.
