does not seem like
Classic euphemism. Try 'isn't'. Short of conceivably convincing reasonable and impartial third parties her actions somehow endangered the life and limbs of multiple people (which for snow blowing seems entirely ridiculous), it's an extremely violent overreaction. Given that police had been to the residence without intervening materially before suggests there was no such reasonable motive for her to be Rashkolnikoved. There seem to be hints in the article (like the wildly contrasting characterizations of the victim) that there some ongoing feud between the parties which strongly suggests other grievances, and the snowblowing may have been the proverbial straw. Maybe there was a property or money dispute, maybe they'd had a tryst and falling out, maybe drugs, seems like Truman Capote stuff.
