Receiving new audio files from the event thanks to @chrismartenson - I will be revising and updating my audio forensics analysis chart. It's now clear there is another round in the "5-round burst" which I had previously identified as only four rounds. It's now being stated that PA law enforcement fired one round, so this will be incorporated into the next analysis.
NEW HALF-SPEED AUDIO, please offer your analysis: Stacked 3 audio sources of the cluster of what seems to be 5 rounds, these were fired after the original 3 rounds. So these are rounds #4-8, which in this case would indicate #9 (10 seconds later or so) as the counter-sniper round. This audio snippet stacks the Fox News feed, a "ROOF" audio file (thanks to @chrismartenson ) and a "near building" audio file which was closer to the building on which Crooks was found.
So the Chief Security Officer of Crowdstrike, who sold 4,000 shares just days before the "IT apocalypse" that wiped hundreds of thousands of government servers (possibly destroying evidence of deep state complicity in the assassination attempt) is an FBI veteran with 24 years with the FBI. Can't make this up. The same agency that's now actively involved in the cover-up.
