A guy that lived down the street when I was growing up in Queens was a business lawyer in Manhattan, not really wealthy, sort of middle class. Our neighborhood was changing and not for the better. He was not, as far as I know, a criminal lawyer. He did defend a guy from Forest Hills (an upscale neighborhood) who murdered his wife in the kitchen. He lost the case, but took the house as his fee. Not a bad moonlighting gig.
I helped him move furniture or something, not for money, as a friendly neighbor kid. I forget the details. But, yes, there was a bloodstain in the kitchen floor.
Lawyers always win
