According to a Tuesday news release, Cameron County’s forensic pathologist determined the cause of death as "acute combined cocaine and fentanyl toxicity."

“The in-custody death of Edgar Hernandez case has been closed,” the release stated. “Hernandez was able to conceal the narcotic to avoid it being found in the search of his person.”

The custodial death report for Hernandez that was filed in January reported that EMS personnel who tended to Hernandez “discovered a piece of white toilet paper containing a small clear plastic bag with a white powdery substance inside of it on Mr. Hernandez’s person.”

The findings of the investigation into Hernandez' to the Cameron County District Attorney's Office, who determined the death was not criminal.
