An official cause of death for George Floyd remains a mystery as the Hennepin County Medical Examiner's Office says it cannot rush the autopsy process.
In a statement released Thursday evening, the medical examiner's office said it is "awaiting final results from laboratory studies to provide the most medically accurate cause of death determination possible."
The statement notes that the medical examiner understands the pressing need to transparency in Floyd's death, which is believed by many to be at the hands of four now-former Minneapolis police officers who were involved in Floyd's arrest Monday night.
"However, the autopsy alone cannot answer all questions germane to the cause and manner of death, and must be interpreted in the context of the pertinent investigative information and informed by the results of laboratory studies," the statement said.
Floyd was pronounced dead at 9:25 p.m. at the Hennepin Healthcare emergency room, where he was transported after losing consciousness while an arresting officer knelt on his neck.
During the approximately seven minutes of available video from the incident at the intersection of 38th St. and Chicago Ave., police officer Derek Chauvin is seen with his knee on Floyd's neck the entire time, even when Floyd repeatedly said "I can't breathe."
It's unclear when an official cause of death will be released by the medical examiner's office.
