This may be enough to open an investigation and start gathering more evidence, but doesn't satisfy probable cause. The cops and court screwed up.

A database match is not enough to confirm that this specific person (may have) committed the crime.

It would be like sending a ransom note asking the money be sent to Joe Smith, 123 Fake St. That doesn't really tell you anything about Joe Smith's connection to the crime. It's completely incidental.
