That’s remotely possible, and I would be inclined to agree if the circumstances around this weren’t so fishy to begin with.

E.g. why is the police report heavily redacted? Why has the suspect not been named? This is highly unusual, and suggests there’s something more going on. I’d doubt very highly the grand jury were given the full picture.

It’s pretty much a done deal that we’ll never know more. Someone is making an effort to bury this.
