One of Mikhail Khachaturyan's three teenage daughters stabbed him fatally in the heart in their Moscow apartment.
According to Newser, the man's murder has refocused attention on domestic violence and sparked a culture-war debate.
Khachaturyan allegedly beat, humiliated, threatened, and sexually abused his three daughters.
When he pepper-sprayed each of them in the face, the girls sprayed him back, beat him with a hammer, and stabbed him to death.
