Jeffrey R. Smith, one usage of "according to court records" would NOT have sufficed for the entire article. If the paper wants to avoid a libel suit, that needs to be in every paragraph at least.
However, the writer should have mixed it up a bit, such as starting a paragraph with "Court records said..." or putting the phrase within the paragraph somewhere.
I suspect the writer turned in the story with no attribution at all, and a hurried editor quickly added those phrases.
