A Portland mother who left her toddler while the child was in medical distress will spend nearly eight years in state prison, after also admitting a role in a later armed carjacking. Mary Jo Jacobo, 26, was sentenced to 7 years, 10 months in the death of her 2-year-old daughter, Aurora Fernandez, under a negotiated plea deal.
Sentence And Courtroom Decision
Multnomah County Circuit Judge Heidi H. Moawad accepted the negotiated resolution and ordered Jacobo to serve 7 years, 10 months in state prison, as reported by OregonLive. The judge credited her with about 1 year and 4 months already spent in custody while the case moved through the courts.
Plea Deal And Charges
According to court filings, Jacobo pleaded guilty to first-degree criminal mistreatment for abandoning her daughter while the toddler was in medical distress. She also admitted to robbery and unauthorized-use charges tied to a Sept. 26 carjacking. Prosecutors said the agreement wraps up several pending cases that dated back to earlier incidents in 2023 and 2024. Details of those arrests were previously reported by KPTV.
What Happened To Aurora Fernandez
On Sept. 12, officers were called to a northeast Portland RV park for a report of a child in cardiac arrest. A friend inside the home performed CPR and called 911, authorities said, but the 2-year-old was taken to a hospital and died that afternoon. Police initially flagged fentanyl as a suspected contributing factor, based on what they found at the scene and what they were told by hospital staff. Good Morning America outlined that sequence of events.
Armed Carjacking And The Victim
Prosecutors also linked Jacobo to a Sept. 26 armed carjacking in north Portland. In that incident, assailants pointed guns, demanded the keys and took off with a silver Toyota Camry. Family members identified the victim as Tyler Nuss and said he suffered a head injury after being struck with a rifle. Police later boxed in an alleged accomplice, who exchanged gunfire with officers and now faces separate charges. The carjacking and the ensuing police confrontation were detailed by KPTV.
Toxicology, Evidence And The Judge’s Remarks
In court, prosecutors and the medical examiner said toxicology tests did not show evidence of what they described as a classic drug overdose, and the child’s cause of death was listed as “undetermined,” Deputy District Attorney Branden J. Meadows told the judge. Prosecutors said officers found pills and a loaded syringe containing a fentanyl and methamphetamine mixture in the room where the child had been located. Judge Moawad urged Jacobo to confront trauma, abuse and her grief over Aurora’s death while serving her sentence. OregonLive provided the courtroom account, and Hoodline previously covered Jacobo’s initial arrest last October in Seaside in an article headlined Arrested In Seaside.
Why The Case Matters
The case has again highlighted the lethal risks fentanyl poses to very young children, along with the tangle of addiction, unstable housing and crime that prosecutors and social service workers confront in Oregon and beyond. Reporters have placed tragedies like Aurora’s within a broader public health emergency that continues to unfold. Good Morning America summarized how investigators are connecting what they found inside that RV to the larger surge in opioid-related harms nationwide.
