I’m hoping this lame story is merely inept lying. If authorities really do believe what they’re spouting in this article, and the man actually “convinced police that his plan was to kill himself in an isolated spot by swallowing the chemicals”, NYC is in deep kimchi.
Like you said, why go to the trouble of dressing as a worker and accessing the tunnels? Even if they could somehow rationalize a QUART of cyanide for a suicide—which is ridiculous—who carries flares when trying to NOT draw attention? That’s freakin what they’re for!
Same... I honestly can’t imagine NYPD buying this story.
