The victim appears to be white-—if he’s black he’s not much blacker than the Pope at best, which in my book isn’t black.
The Pope is definitely blacker than I am, but my blackest ancestors could pass (and fight) as white by 1861-—and named their son Jefferson Davis just in case anyone was unsure about their views on who ought to be in charge in Missouri.
Well, the killer dude is at least 50% white, per the nose and skin tone. Mulatto, maybe even a quadroon.
