"The new autopsy results, released Wednesday, said that Gonzalez died on April 19, 2021, from “restraint asphyxiation,” according to forensic pathologist Bennet Omalu.
The independent autopsy, which was requested by the family’s attorneys, according to the San Francisco Chronicle, countered the report from the Alameda County coroner’s office last year, which had called the death a homicide but listed the principal cause as “toxic effects of methamphetamine.” The report included under other “significant conditions” the “physiological stress of altercation and restraint,” as well as “obesity” and “alcoholism.”
