In 1987 he dismembered the body of Steve Tuomi, 25, in his grandmother’s basement.

Did Catherine Dahmer know her grandson was a serial killer?


As Jeff lived with her when he was arrested for indecent exposure, and child sex assault charges, Catherine would have known that her eldest grandson was troubled. But, if we are going from what we have seen on Ryan Murphy's Netflix series, she was in denial that Jeff was gay, so might also have been able to ignore any other troubling signs of what he was really getting up to, and what was causing the terrible smells underneath her home.
