I filed a public records request for it today. Frankly, I'm doubtful that I'll receive anything. The woman I spoke with on the phone said that unless it was deemed "historical" in nature that the record had likely been destroyed.
While the event might be historical in retrospect, I'm not sure it was deemed that in the past. My guess is that any police or incident reports from 50 years ago were thrown in the shredder long ago.
If, by a miracle, I get my hands on it, I'll be sure to share it.
