Demented trolls are poking fun at one of the NYC shooter's victims this week ... saying a corporate real-estate executive got "LUIGI'D" -- a reference to alleged UnitedHealthCare CEO killer Luigi Mangione.
Social media scoundrels posted a photo on X of a woman named Wesley LePatner -- senior managing director of Blackstone -- who was one of 4 people fatally shot by Shane Tamura inside a Manhattan skyscraper Monday night before he took his own life.
