You asked what a domme/mistress might be charged with in the US or the English speaking lands if and when a similar situation took place.

I think we know, in part, because of the July 2000 case of Barbara Asher. Asher was accused of manslaughter based on her own unrecorded confession which was later denied or retracted. No body was ever found and the jury ended up acquitting her, even though she might have been guilty. There is also the Daniel Penny case with the black homeless guy on the subway!

However, there were two many questionable facts to make a guilty verdict easy.

Anyway, back in July 2000, a Quincy, Massachusettes domme with a makeshift dungeon saw a client. The client was overweight and may have had other health problems.

Anyway, she was charged with involuntary manslaughter and not with murder. The guy reportedly had a heart attack and for several minutes she did not take action to save his life, or so it was claimed by the prosecution.

I think that there are usually 2 degrees of manslaughter and that the involuntary manslaughter is the least serious of the manslaughter charges.

I think that involunary manslaughter is about the same as negligent homicide, the charge in the German strangling case!

Oh, I am missing something. For example, in the case of Daniel Penny, he was charged with both manslaughter and "negligent homicide." The manslaughter charge was more serious and was dismissed first, and then, after a little more deliberation, the jury found not guilty on the negligent homicide charge.
