Any argument you can devise for this relies utterly on the critical step "a murderer acts on information in the article". The murderer was always the one placing people's lives at risk. And the murderer could also subscribe to the very same services which index public documents and court filings daily, that newspapers often use--like LexisNexis, for instance. Users can even be alerted on certain names and keywords. The LA Times article publication isn't even a critical step!
Even "a person is shocked/scared to death by the published information" would require some physiological condition that would enable someone to drop dead from an emotional response, such as heart disease with ventricular fibrillation, or organ failure due to chronic cortisol and adrenaline poisoning.
Perhaps publication of a paradox, like "This article contains no true statements," would kill an overly-logical AI?
The crime triangle of motive, method, and opportunity is closed by the criminal--the one with mens rea, the evil motive--not by anyone who produced any element of the opportunity.
Your assertion is completely unsupportable, and indirectly hostile to freedom of speech, by attributing imagined harms to speech, when their ultimate causes lie elsewhere.
