The newly released autopsy report details Deshaun’s medical history, which allegedly showed that he had historically had trouble gaining weight. He had been hospitalized as a newborn after suffering from sepsis and a urinary tract infection that caused him to vomit after every feeding. After remaining in the hospital for 10 days, he was discharged, and his parents were advised on how to improve Deshaun’s nutrition.
According to the autopsy, Deshaun was 34 lbs. at age 4, but weighed only 18 lbs. when he died.
The arrest records allege Elizabeth Archibeque told officers that Deshaun did not gain weight, despite being “fed a lot.” Anthony Martinez allegedly told police that they were on a budget and would have bought better food for Deshaun after receiving their next food stamps.
PEOPLE confirms that all three defendants have pleaded not guilty and are being held on $3 million bond. Court records do not reflect attorneys authorized to speak on their behalf, but indicate that they will be represented by a public defender. Fox 10 reports that the public defender’s office has not yet assigned an attorney to the cases.
Prosecutors have until late July to decide whether they will seek capital punishment in the case.
