Justicia para el pequeño Gabriel

Dark details of Gabriel's story come to light as a shadowy source from inside the DCFS suggests that his case wasn't handled properly.

With hundreds of witnesses and thousands of documents, the trial of Isauro Aguirre begins — with Deputy DA Jonathan Hatami seeking the death penalty.

Focus shifts to Gabriel's mother, Pearl, and the role she may have played in his death. Gabriel's teacher recounts a series of calls to child services.

At Isauro's trial, a former security guard details his attempts to help Gabriel that hit a dead end with social services and the sheriff's department.

The social workers fight to clear their names in court. Later, with the cameras turned off, Gabriel's siblings take the stand and give graphic testimony.

As LA County assesses the cracks of a broken system, the jury reaches a verdict in Isauro's case, and Pearl Fernandez has her day in court.
