Just a status report: Police are still tying up loose ends in the Chris Brown investigation. The L.A. County D.A. does not have the case for review -- at least not yet.

The D.A. sent the case back to the LAPD last month to further investigate the allegation that Brown made criminal threats against Rihanna.

We just checked with the D.A. -- the LAPD has not presented the case to them.
