Last December, a jury recommended Aguirre be sentenced to death after convicting him of first-degree murder and the special circumstance allegation of murder involving torture.
Fernandez pleaded guilty to first-degree murder in February. She admitted to the torture special circumstance allegation in exchange for a life prison term without the possibility of parole. She had been facing a possible death sentence if the case against her had gone to trial and if she had been convicted as charged.
Gabriel was routinely beaten, shot with a BB gun, fed cat feces and forced to sleep while gagged and bound inside a small cabinet, witnesses and prosecutors said. He died in May 2013.
The judge is expected to allow family and friends to read victim-impact statements before the two are sentenced.
