Hypoxic-ischemic brain injury (inadequate blood flow/oxygenation of the brain)
"Accidents, heart attacks and strokes can deprive the brain of oxygen, leading to cerebral hypoxia. Cerebral hypoxia is a medical emergency. It can cause permanent brain injury. If the brain goes too long without oxygen, brain death and coma can occur."
If the oxygen supply to the brain is interrupted, the functioning of the brain is disturbed immediately and irreversible damage can quickly follow. Get info on the causes, effects, treatment and rehab.

The results of the autopsy remind me of several deaths I know of that were caused by positional asphyxiation. Since it seems there isn't evidence that she had a heart attack, was strangled or manually suffocated, maybe she was unconscious or passed out/fell asleep. A mild concussion could be a part of that. Sleeping in a position that prevents the lungs from expanding and getting enough oxygen, or getting accidentally stuck in a position, like draped over the side of the bathtub. If someone beat you up and left you in a folded-over position if you have a nonfatal concussion and a bruised forehead and with uncooperative witnesses, I can see how the federal prosecutor would say the evidence does not support a federal prosecution.

From the article the statement by the federal prosecutor:
“Based on the results of the autopsy and after a careful deliberation and review of the investigative materials by both U.S. Attorneys’ Offices, federal prosecutors informed Ms. Robinson’s family today that the available evidence does not support a federal prosecution.”
Federal prosecutors will not file criminal charges in the death of Shanquella Robinson, they announced in a statement Wednesday.

From the article linked below:
"The medical examiner said that based on the autopsy results, Robinson’s cause of death is undetermined, but that the most significant findings were hematoma of the forehead (pool of blood that forms in an organ, tissue, or body space), mild cerebral edema (concussion), and hypoxic-ischemic brain injury (inadequate blood flow/oxygenation of the brain)."
An autopsy of Shanquella Robinson conducted in Charlotte found Robinson’s spine intact.
