Was this the coroner or medical examiner? I didn't think the coroner did a report. The medical examiner released their full report shortly after the preliminary one and did state the death was ultimately due to asphyxiation. I read that the initial medical examiner's report didn't go this far b/c they had not completed their review and they needed to get a report out quickly so that the officers could be charged.

IIRC we're talking about the initial report. Later on, they backtracked, but their original report was patently flawed. Given the direction and obviousness of the flaws, one must question whether the flaws were only due to haste.
